Moldex 6800 Pura-Fit Uncorded Foam Earplugs — NRR 33, 200 Pairs

Moldex 6800 Pura-Fit Overview

The Moldex 6800 Pura-Fit is a single-use polyurethane foam earplug rated NRR 33 — the highest Noise Reduction Rating available for in-ear hearing protection — sold uncorded in a 200-pair box. Its tapered, low-pressure foam is engineered to expand gently inside the ear canal, so it seals to the rated attenuation without the tight, aching fit that drives workers to pull plugs out mid-shift. It is the workhorse plug a safety manager buys when the goal is maximum protection that crews will actually keep wearing.

Where the Pura-Fit Fits in Hearing-Protection Selection

Start by confirming the hazard: continuous or intermittent industrial noise at or above the OSHA action level of 85 dBA. Foam plugs like the Pura-Fit are a primary control for that exposure. Confirm the rating you actually need before defaulting to the maximum — more NRR is not always better, because over-attenuation can isolate a worker from alarms and speech. Our explainer on what NRR means and how to derate it walks through the math, and OSHA 29 CFR 1910.95 hearing conservation covers the program requirements.

Who Should Buy the Moldex 6800 Pura-Fit?

• Buy it if you need maximum NRR 33 attenuation for all-day wear and comfort drives compliance on your crew.
• Buy it if you run a bulk program — the 200-pair box is the lowest cost-per-use way to keep a line stocked, especially paired with a wall dispenser.
• Choose corded instead if workers remove plugs often: the Moldex 6900 Pura-Fit Corded keeps the pair together. Compare the trade-off in corded vs cordless ear plugs.
• Choose a reusable plug instead if plugs come in and out dozens of times a shift — washable flanged reusable ear plugs cost less over time.
• Choose a detectable plug instead for food, beverage, or pharma lines — the metal-detectable Moldex 6615 SparkPlugs.

What Does the Pura-Fit Protect Against?

What the Pura-Fit Does NOT Protect Against

• It is not a substitute for engineering or administrative noise controls where those are feasible.
• It does not provide situational awareness or communication — for that, see level-dependent electronic muffs.
• It is not metal-detectable, so it is not suitable for food, beverage, or pharmaceutical production lines.

Important: A foam earplug only delivers its rated NRR when rolled down tightly and inserted deeply enough to expand inside the canal. OSHA and NIOSH both recommend derating the labeled NRR in the field when estimating real-world protection. Confirm fit, train workers, and verify exposure with a hearing-conservation program — do not rely on the rated number alone.

Best Applications

Manufacturing & fabrication

For steady plant noise, the Pura-Fit's NRR 33 and all-day comfort make it the default issue plug. Keep it stocked at the line with ear plug dispensers to drive usage.

Construction & jobsites

High intermittent noise from saws, breakers, and heavy equipment suits a high-NRR foam plug. See jobsite-specific picks in our best ear plugs for construction guide and the construction hearing protection collection.

Maximum-protection programs

When the spec calls for the top rating, the Pura-Fit sits among the highest-NRR ear plugs. It is also a cordless, disposable plug, so each wear is sanitary.

Compatible Moldex Dispensers & Refills

The 6800 Pura-Fit is the refill plug for Moldex's Pura-Fit dispenser stations — the simplest way to keep a fresh pair within reach and control usage at entry points.

The uncorded 6800 does not fit corded-plug stations — for a corded Pura-Fit dispenser use the 6882 PlugStation Corded with the corded 6900 plug.

Pura-Fit vs Other Moldex Foam Earplugs

Pura-Fit vs Softies 6600

Both are uncorded NRR 33 Moldex foam plugs. The Pura-Fit uses a tapered, low-pressure body that suits the widest range of ear canals; the Softies 6600 uses an even softer, smaller-diameter foam aimed at workers who find standard plugs too large. Verdict: default to the Pura-Fit for a mixed crew; switch to Softies for workers reporting a too-tight fit.

Pura-Fit Uncorded vs Pura-Fit Corded 6900

Same foam, same NRR 33 — the only difference is the cord. Choose the uncorded 6800 for continuous wear at the lowest cost; choose the corded 6900 when plugs come out frequently or a dropped plug is a contamination risk. Verdict: the cord is a workflow decision, not a protection one — see corded vs cordless ear plugs.

Pura-Fit vs Howard Leight Max-1

The two benchmark NRR 33 disposable foam plugs. The Pura-Fit leads on low insertion pressure for comfort; the cross-brand Howard Leight Max-1 is the best-selling universal-fit bell shape. Verdict: read the full head-to-head in Moldex Pura-Fit vs Howard Leight Max-1.

Pura-Fit Quick Answers

What is the NRR of the Moldex 6800 Pura-Fit?

The Moldex 6800 Pura-Fit is rated NRR 33, the highest Noise Reduction Rating available for an in-ear plug under the EPA/ANSI labeling system.

How many earplugs are in a box?

Each 6800 box contains 200 individually packaged uncorded pairs — a bulk quantity sized for hearing-conservation programs.

Is the Pura-Fit corded or uncorded?

The 6800 is uncorded. The corded version is the Moldex 6900 Pura-Fit, which carries the same NRR 33 foam.

Is the Moldex 6800 reusable?

No. It is a single-use disposable foam plug; foam absorbs wax and grime and loses its seal, so each wear should use a fresh pair.

Which dispenser refills the 6800 Pura-Fit?

Moldex Pura-Fit PlugStation and EcoStation dispensers (6844, 6845, 6705, 6535, 6835) are built for the uncorded 6800.

Moldex 6800 Pura-Fit Frequently Asked Questions

How much does a box of Moldex 6800 Pura-Fit cost?

WC Safety lists the 200-pair box at $43.00, which works out to roughly $0.22 per pair — among the lowest cost-per-use for an NRR 33 plug.

Are these the same plugs sold in Moldex dispensers?

Yes — the uncorded 6800 Pura-Fit is the refill plug for Moldex Pura-Fit PlugStation and EcoStation dispensers, so you can buy boxes and dispenser refills of the same plug.

Do I need corded plugs for my crew?

Only if workers remove plugs frequently or a dropped plug is a contamination hazard. For continuous wear, the uncorded 6800 is cheaper; otherwise order the corded 6900 Pura-Fit.

What size are Pura-Fit earplugs?

The Pura-Fit is a one-size tapered plug designed to fit the majority of adult ear canals. Workers who find it too large often prefer the smaller-diameter Moldex 6600 Softies.

Are Moldex 6800 earplugs latex-free?

Yes — they are made of polyurethane foam and contain no latex, which suits facilities with latex-allergy policies.

Can I use these for shooting or the range?

They will attenuate gunfire, but most shooters prefer level-dependent protection that preserves range commands; see the shooting hearing-protection collection for those options.

How do I insert the Pura-Fit correctly?

Roll the plug into a thin crease-free cylinder, reach over your head to pull the ear up and back, insert past the canal opening, and hold for 20–30 seconds while it expands.

Do Moldex foam earplugs expire?

Unused plugs keep for years if stored clean and dry, but Moldex lists a shelf life because foam can stiffen over time, which slows expansion and weakens the seal.

Is the Moldex 6800 OSHA compliant?

OSHA does not approve individual plugs; any NRR-labeled plug can anchor a compliant program under 29 CFR 1910.95 when the NRR is adequate for the exposure and the plug is fitted correctly.

How many boxes do I need for my workforce?

Plan one pair per worker per shift for uncorded plugs. A 200-pair box covers a 25-person crew for about eight shifts; pair it with a wall dispenser to control usage.

What's the difference between Pura-Fit and SparkPlugs?

The SparkPlugs are the metal-detectable version for food and pharma lines. If you do not need detectability, the Pura-Fit is the lower-cost choice at the same NRR 33.

Does WC Safety ship the Moldex 6800 in bulk?

Yes — the standard pack is the 200-pair box, and Pura-Fit dispenser refills are available up to 750 pairs for high-traffic stations.
