corded glide-trio moldex nrr-27 reusable-earplugs triple-flange twist-in

WC Safety Rating: 4.5 / 5

"The Glide Trio solves a real problem: some workers have the dexterity to twist a flanged plug into position, others prefer the straight push-in method — and the Glide Trio handles both. The slick Glide coating eliminates the dry-drag friction that makes some flanged plugs difficult to seat correctly, and NRR 27 handles most industrial environments without dual protection. The single corded configuration is the only limitation; if you need an uncorded version, the Jetz or Rockets are the call."

Moldex Glide Trio Reusable Earplugs — Dual-Insertion Triple-Flange, NRR 27

The Moldex Glide Trio (6445) is a reusable triple-flange earplug that solves one of the most common barriers to correct flanged earplug use: insertion friction. Moldex's proprietary Glide surface coating reduces drag so the triple-flange stem glides into the ear canal smoothly whether the worker uses a push-in or twist-in insertion method. Either technique seats all three flanges correctly, forming an NRR 27 acoustic seal without the force-fitting that causes workers to give up on reusable earplugs after the first week.

The Moldex earplugs line uses the Glide coating across several products — the Glide foam earplugs (6940) and Glide Soothers (6980) bring the same concept to disposable foam. The Glide Trio extends it to a reusable flanged format, combining the coating's insertion ease with the durability and cost efficiency of a washable, multi-use design. Latex-free, PVC-free, and antimicrobial.

Quick Facts — Moldex Glide Trio

    What makes the Glide Trio unique: The Glide surface coating reduces insertion friction so the triple-flange stem slides into position cleanly whether the worker pushes straight in or rotates the stem while inserting. No dry-drag resistance that can cause workers to seat the plug incompletely. This is the only Moldex reusable earplug with the Glide coating.
  

Key Features

🔇

NRR 27 Triple-Flange Seal Three graduated flanges create an acoustic seal by contact — no foam expansion wait time. Flanges conform to individual canal geometry for consistent NRR 27 attenuation.

✨

Glide Surface Coating Moldex's proprietary low-friction coating eliminates the drag that makes conventional flanged plugs difficult to insert correctly. Workers can push-in or twist-in — both result in a proper seal.

🔄

Push-In or Twist-In Insertion Unlike most flanged plugs that require a specific insertion technique, the Glide Trio accepts either method — accommodating workers with different dexterity levels or gloved-hand limitations.

🦠

Antimicrobial Formula Built-in antimicrobial compound inhibits bacteria growth between uses, extending safe daily wear and simplifying between-shift hygiene.

🧪

Latex-Free & PVC-Free Safe for workers with latex sensitivity. No PVC or phthalates in the elastomer compound.

🧺

Washable & Reusable Wash with soap and warm water. Inspect flanges before each use. Replace when flanges crack, deform, or no longer seat snugly.

Insertion Methods — Push-In vs. Twist-In

Method	How to Do It	Best For
Push-In	Pull ear up and back with opposite hand; insert stem straight into canal until outermost flange seats at the canal opening	Workers who prefer simple straight insertion; faster entry/exit situations
Twist-In	Pull ear up and back with opposite hand; insert stem while gently rotating it — similar to a screw motion — until all flanges are seated	Workers with narrow or curved canal geometry; those who find push-in creates resistance with standard flanged plugs

With conventional flanged plugs, the dry-drag friction often results in workers stopping short of a full seal — leaving one or more flanges outside the canal and significantly reducing effective attenuation. The Glide coating eliminates this by allowing the stem to move freely regardless of technique.

Applications

Workers New to Flanged Earplugs

Workers transitioning from foam disposables to reusable flanged plugs often struggle with the insertion technique. The Glide coating removes the friction barrier, and the dual-method acceptance means workers can use whatever feels natural rather than being corrected back to a single prescribed technique.

Gloved-Hand Environments

Chemical, food processing, and cleanroom environments where workers wear gloves present a dexterity challenge for standard flanged plug insertion. The Glide Trio's low-friction surface means workers can seat the plug correctly even through nitrile or latex gloves without losing grip.

Repeat-Entry Zones

The flanged reusable design eliminates the 30-to-60-second foam expansion wait on re-insertion. Workers moving frequently between quiet and noisy areas can re-seat the Glide Trio in seconds — and the Glide coating means correct seating on every insertion, not just the first.

Moderate-to-High Industrial Noise

At NRR 27 with 10 dB effective attenuation (OSHA 50% derating), the Glide Trio handles most manufacturing, construction, and utilities environments up to approximately 100 dBA TWA without requiring dual protection.

OSHA 29 CFR 1910.95 Compliance Note

Under OSHA's hearing conservation standard, the Moldex Glide Trio (NRR 27) provides 10 dB effective attenuation when OSHA's 50% derating is applied: (27 – 7) × 0.5 = 10 dB.

Workplace TWA (dBA)	Effective Level at Ear	OSHA Compliant?
90 dBA (PEL)	80 dBA	Yes — 10 dB margin
95 dBA	85 dBA	Yes — at action level
100 dBA	90 dBA	Yes — meets PEL
105 dBA	95 dBA	No — dual protection required

For environments consistently above 100 dBA TWA, dual protection (earplug + earmuff) is required. Confirm effective protection through audiometric testing as mandated by 29 CFR 1910.95(g).

Frequently Asked Questions — Moldex Glide Trio

What is the NRR of the Moldex Glide Trio?

The Glide Trio carries an NRR of 27 dB, tested per ANSI S3.19-1974. Applying OSHA's 50% real-world derating formula yields 10 dB effective attenuation — adequate for most industrial environments up to approximately 100 dBA TWA.

What makes the Glide Trio different from other Moldex reusable earplugs?

The Glide Trio is the only Moldex reusable earplug with the Glide surface coating. This low-friction coating allows push-in or twist-in insertion — both methods result in a correct seal — whereas standard flanged plugs rely on a single insertion technique and can be difficult to seat when friction causes premature resistance mid-insertion.

Can I use the Glide Trio without a cord?

The Glide Trio (6445) is currently offered in a corded configuration only. If you need an uncorded reusable earplug at NRR 27, consider the Moldex Rockets 6400 or Jetz 6450 (both uncorded, NRR 27, triple-flange).

How do you insert the Glide Trio?

Pull your ear up and back with the opposite hand to straighten the canal. Insert the Glide Trio stem-first using either a straight push-in or a gentle twisting motion. Continue until the outermost flange sits at the canal opening and all three flanges are inside the canal. The Glide coating allows the stem to move freely with either technique. Release your ear.

Is the Glide Trio washable?

Yes. Wash with mild soap and warm water, rinse thoroughly, and air-dry before reuse. Do not use solvents or bleach — these degrade the elastomer and can affect the Glide surface coating. Replace when flanges show visible cracking, permanent deformation, or fail to create a snug seal.

Is the Glide Trio latex-free?

Yes. The Glide Trio is made from a latex-free, PVC-free elastomer compound — safe for workers with latex allergies or facilities with latex-restriction policies.

How does the Glide Trio compare to the disposable Moldex Glide foam earplug?

Both use Moldex's Glide surface coating to reduce insertion friction. The foam Glide (6940/6945, NRR 30) is a disposable single-use plug for dispenser programs — higher NRR, no rolling required, single shift per pair. The Glide Trio (6445, NRR 27) is a washable reusable for multi-shift programs. Choose foam Glide for disposable dispenser programs; choose Glide Trio where reusability and cost-per-use savings matter.

How long do the Glide Trio earplugs last?

With daily use and proper cleaning, most workers replace the Glide Trio every 1–2 weeks. Replace immediately if flanges crack, tear, permanently compress, or no longer create a firm seal. The Glide surface coating durability holds up to normal washing cycles; abrasive cleaning tools can degrade the coating faster.

Is the Glide Trio made in the USA?

Yes. Moldex Glide Trio earplugs are manufactured in the United States, consistent with Moldex's domestic production commitment across their hearing protection line.

Does the Glide Trio work with other PPE like safety glasses or hard hats?

Yes. The flanged stem design does not wrap around the ear, so the Glide Trio is compatible with safety glasses, face shields, hard hats, and respirator straps without pressure interference. The cord hangs at the neck when the plugs are removed, keeping them accessible and out of the way of other equipment.

What is the pack size for the Glide Trio?

The Glide Trio 6445 is packaged in pairs. Contact WC Safety for quantity pricing on bulk orders for safety program issue.

Is there a dispenser option for the Glide Trio?

The Glide Trio is a reusable product individually issued to workers — it is not designed for bulk dispenser programs. For wall-mount dispenser programs, consider the Moldex Glide foam earplugs (6940/6945) compatible with the PlugStation, or Pura-Fit/SparkPlugs for EcoStation dispensers.
