NRR 27 handles the bulk of industrial noise environments, the antimicrobial formula keeps them safe for multi-shift use, and the Pocket Pak format means workers can always have a fresh pair on them. If you want Moldex reusable comfort at a step below the Alphas' price point, the Jetz deliver."

Moldex Jetz Reusable Earplugs — Extra-Soft Triple-Flange Comfort, NRR 27
The Moldex Jetz are reusable triple-flange earplugs built for workers who re-enter high-noise zones repeatedly across a shift and need protection that stays comfortable after the sixth or seventh insertion of the day. The extra-soft elastomer formula reduces the ear-canal pressure that makes stiffer flanged plugs uncomfortable over time, while the triple-flange stem creates a reliable acoustic seal without the finesse required by foam roll-down plugs.
Moldex earplugs are engineered and manufactured in the USA, and the Jetz continue that tradition with a latex-free, PVC-free compound that carries Moldex's built-in antimicrobial protection — inhibiting bacteria growth between uses so a single Pocket Pak pair can serve a full work week when cleaned regularly. NRR 27 provides 10 dB of effective attenuation under OSHA's 50% derating formula, adequate for most manufacturing, utilities, and construction environments up to approximately 100 dBA TWA.

Key Features
🔇
NRR 27 Triple-Flange Seal
Three graduated flanges compress independently to conform to individual ear canal contours — no single-size-fits-all compromise.
🤲
Extra-Soft Elastomer
Softer than standard flanged reusables — reduces canal pressure and spring-back discomfort that builds up over a long shift with repeated insertions.
🦠
Antimicrobial Formula
Moldex's built-in antimicrobial compound inhibits bacteria growth on the plug surface — cleaner between daily uses without additional treatment.
🧪
Latex-Free & PVC-Free
Safe for workers with latex sensitivity or chemical restrictions. No PVC or phthalates.
🧺
Washable & Reusable
Clean with soap and warm water. Inspect flanges before each use; replace when flanges show cracking, deformation, or permanent compression.
🎒
Pocket Pak Format
50 pairs per resealable Pocket Pak bag — compact enough for a tool belt pouch or safety supply cabinet drawer.
Model Variants
| Model | Description | NRR | Pack |
|---|---|---|---|
| 6450 | Jetz — uncorded | 27 | 50 pairs / Pocket Pak |
| 6455 | Jetz — corded | 27 | 50 pairs / Pocket Pak |
Corded (6455) vs. uncorded (6450): The corded version keeps the pair connected when removed — ideal for jobs where plugs come out frequently (talking to a supervisor, answering a radio) and re-insertion is common. The cord reduces the chance of losing or dropping one plug in a dirty or wet environment. Uncorded suits workers who prefer a cleaner feel or who remove plugs less frequently.
Moldex Reusable Earplug Comparison

|---|---|---|---|
| Rockets 6400 | 27 | Triple-flange | 7 variants incl. metal-det., camo; widest selection |
| Jetz 6450 This Product | 27 | Triple-flange extra-soft | Softest flange formula; best for sensitive canals |
| Alphas 6430 | 27 | Multi-flange ultra-soft | 3-position wear; softest overall; Pocket Pak Plus case |
| Glide Trio 6445 | 27 | Triple-flange | Twist-in or push-in insertion; unique dual-method |
Applications
Manufacturing & Assembly
The combination of easy flanged insertion and extra-soft material makes the Jetz well-suited to manufacturing floors where workers enter and exit high-noise machinery zones repeatedly. The reusable format reduces daily earplug consumption and the waste management burden compared to disposable foam programs.
Construction & Utilities
Workers operating saws, compressors, or generators benefit from NRR 27's 10 dB effective attenuation. The antimicrobial compound is practical on job sites where plugs spend time in a dirty tool belt or vest pocket between uses.
Repeat-Entry Environments
Any application where workers regularly move between quiet and noisy zones — utilities substations, pump rooms, HVAC work — the flanged design's no-memory insertion (no roll-and-wait like foam) means re-insertion takes seconds rather than the 30–60 seconds required for foam to expand to a full seal.
Workers with Foam Sensitivity
Some workers find foam roll-down plugs uncomfortable due to the expansion pressure inside the canal. The Jetz flanged design creates an acoustic seal through contact without expansion pressure, making them a recommended alternative for workers who resist hearing protection compliance due to foam discomfort.
OSHA 29 CFR 1910.95 Compliance Note
Under OSHA's hearing conservation standard, the Moldex Jetz (NRR 27) provide 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 above 100 dBA TWA, pair with NRR 27+ earmuffs (dual protection) or upgrade to a higher-rated protector. Always confirm fit through audiometric testing as required by 1910.95(g).
Frequently Asked Questions — Moldex Jetz
What is the NRR of the Moldex Jetz?
The Jetz carry an NRR of 27 dB, tested per ANSI S3.19-1974. Under OSHA's real-world 50% derating formula, effective attenuation is 10 dB — adequate for noise environments up to approximately 100 dBA TWA.
What is the difference between model 6450 and 6455?
Model 6450 is uncorded; model 6455 includes a cord connecting the two plugs. Both provide identical NRR 27 protection and come in 50-pair Pocket Pak bags. Choose corded if workers frequently remove and reinsert plugs throughout a shift.
How do you insert the Moldex Jetz correctly?
Hold the stem between thumb and forefinger. Reach over your head with the opposite hand to pull your ear upward and outward, opening the canal. Insert the Jetz stem-first until the outermost flange rests at the canal opening. All three flanges should be inside the canal. Release your ear. No rolling, no waiting for foam to expand.
How long do the Jetz last before they need to be replaced?
Moldex recommends replacement when flanges show visible cracking, tearing, permanent deformation, or if the plug no longer creates a snug seal. With daily use and proper cleaning, most workers replace their Jetz every 1–2 weeks. The Pocket Pak format (50 pairs) supports a team replacement cycle.
Can the Jetz be washed and reused?
Yes. Wash with mild soap and warm water, rinse thoroughly, and allow to air-dry completely before reuse. Do not use solvents, alcohol, or bleach — these degrade the elastomer. The antimicrobial compound in the formula supplements (but does not replace) routine cleaning.
Are the Jetz latex-free?
Yes. Moldex Jetz are made from a latex-free, PVC-free elastomer compound — safe for workers with latex allergies or in facilities with latex-restriction policies.
How do the Jetz compare to the Moldex Rockets?
Both are triple-flange reusables with NRR 27. The Jetz use an extra-soft elastomer formula that is gentler on sensitive ear canals. The Rockets offer a wider variant selection — 7 options including metal-detectable and camouflage. For maximum comfort, choose the Jetz; for variant flexibility (metal detectable, cloth cord, camo), choose the Rockets.
How do the Jetz compare to the Moldex Alphas?
The Alphas (NRR 27) use an ultra-soft multi-flange design that supports three wearing positions (stem up, stem down, cord over ear) and come in a Pocket Pak Plus case with an attached cleaning brush. The Jetz are simpler and less expensive. Both are excellent for sensitive canals; the Alphas offer more fit flexibility and come with a storage case.
What pack size do the Jetz come in?
Both models (6450 uncorded, 6455 corded) come in Pocket Pak bags of 50 pairs each. This format is designed for small-team or individual-issue safety programs. For larger programs, order multiple bags or contact WC Safety for volume pricing.
Are the Jetz made in the USA?
Yes. Moldex Jetz are manufactured in the United States, consistent with Moldex's commitment to domestic production across their hearing protection line.
Do the Jetz work with safety glasses or face shields?
Yes. The flanged stem design does not loop around the ear (unlike banded earplugs), so the Jetz are compatible with safety glasses, face shields, hard hats, and respirator straps. The corded version (6455) hangs at the neck when removed, out of the way of other PPE.
Is there a dispenser option for the Jetz?
The Jetz are packaged in Pocket Pak bags for individual issue rather than in a bulk dispenser format. For high-traffic areas requiring a wall-mount dispenser program, consider Moldex disposable foam earplugs that are available in EcoStation and PlugStation dispensers. See the full Moldex earplugs collection for dispenser-compatible options.
