Moldex 6900 Pura-Fit Corded Foam Earplugs — NRR 33, 100 Pairs

Moldex 6900 Pura-Fit Corded Overview

The Moldex 6900 Pura-Fit Corded is the tethered version of Moldex's flagship foam plug — the same NRR 33 low-pressure polyurethane foam as the uncorded 6800, joined by a cord so the pair stays together when workers pull plugs out. It is sold in a 100-pair box and is the right choice when protection has to come in and out repeatedly without plugs getting lost or dropped into product. Browse the full lineup in corded ear plugs and foam ear plugs, or compare the cord decision in our corded vs cordless ear plugs guide.

Where the 6900 Pura-Fit Fits in Hearing-Protection Selection

Confirm the hazard first: continuous or intermittent industrial noise at or above the OSHA 85 dBA action level. The 6900 carries the maximum in-ear rating of NRR 33, so the protection question is settled — the real decision is corded versus uncorded, which is a workflow choice, not a protection one. If workers wear plugs continuously, the uncorded 6800 costs less; if they remove plugs often, the cord earns its keep. Read what NRR means and how to derate it and the program rules in OSHA 29 CFR 1910.95 hearing conservation.

Who Should Buy the Moldex 6900 Pura-Fit Corded?

• Buy it if workers move in and out of noise and need the pair kept together at the neck.
• Buy it if a dropped plug is a contamination risk and you still need maximum NRR 33.
• Choose uncorded instead for continuous wear at the lowest cost — the 6800 Pura-Fit in a 200-pair box.
• Choose reusable instead if plugs come in and out dozens of times a shift — washable reusable ear plugs cost less over time.
• Choose detectable instead for food and pharma lines — the corded metal-detectable Moldex 6615 SparkPlugs.

What Does the 6900 Pura-Fit Protect Against?

What the 6900 Pura-Fit Does NOT Protect Against

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

Important: A foam earplug only delivers its rated NRR when rolled down tightly and inserted deeply enough to expand in the canal. OSHA and NIOSH recommend derating the labeled NRR in the field. Train workers, confirm fit, and verify exposure within a hearing-conservation program — do not rely on the rated number alone.

Best Applications

Intermittent-noise tasks

Maintenance, inspection, and equipment operators who step in and out of noise all shift are the core use case; the cord keeps protection within reach. See the construction hearing protection range for jobsite needs.

Contamination-sensitive areas

Where a loose plug dropped into product or machinery is unacceptable, a corded plug is the safer issue. For detectable requirements, step up to the metal-detectable ear plugs range.

Maximum-protection programs

At NRR 33 the 6900 sits among the highest-NRR ear plugs; see top foam picks in our best foam ear plugs guide.

Compatible Moldex Dispensers

The corded 6900 is dispensed from Moldex's corded PlugStation rather than the uncorded stations.

For uncorded dispenser stations, use the uncorded 6800 Pura-Fit instead.

6900 Pura-Fit vs Other Moldex Foam Earplugs

6900 Corded vs 6800 Uncorded

Same foam, same NRR 33 — the cord is the only difference. Choose the 6900 corded when plugs come out frequently or a dropped plug is a contamination risk; choose the 6800 uncorded for continuous wear at the lowest cost (and a 200-pair box). Verdict: match the cord to the workflow — details in corded vs cordless ear plugs.

6900 Corded vs Reusable Corded Plugs

If workers reinsert plugs constantly, a washable corded plug like the Moldex 6405 Rockets (NRR 27) pushes in without rolling and lasts weeks. Verdict: the 6900 wins on NRR and hygiene-per-wear; the Rockets win on cost-per-wear — see foam vs reusable ear plugs.

6900 Pura-Fit Quick Answers

What is the NRR of the Moldex 6900 Pura-Fit Corded?

NRR 33 — the same maximum in-ear rating as the uncorded 6800 Pura-Fit.

How many pairs are in a box?

The 6900 ships 100 corded pairs per box.

Is this the same foam as the 6800?

Yes — identical low-pressure Pura-Fit foam; the only difference is the attached cord.

Can I reuse the 6900?

No. It is a single-use foam plug; the cord aids retention, not reuse.

Which dispenser fits the corded 6900?

The Moldex 6882 Pura-Fit PlugStation Corded; uncorded stations do not feed corded plugs.

Moldex 6900 Pura-Fit Corded Frequently Asked Questions

How much does the Moldex 6900 cost?

WC Safety lists the 100-pair corded box at $38.56.

Why choose corded over uncorded plugs?

The cord keeps the pair together when workers remove plugs between tasks and prevents a loose plug from dropping into product or machinery.

Does the cord reduce the NRR?

No — the 6900 is rated NRR 33, the same as the uncorded 6800. The cord does not affect attenuation.

Are the 6900 earplugs latex-free?

Yes, they are polyurethane foam and contain no latex.

Is the cord detachable?

No — the cord is permanently attached and the plug is single-use; discard the pair when soiled.

Can I wash and reuse them?

No. For washable plugs choose flanged reusables such as the Moldex 6405 Rockets.

How do I insert the 6900 correctly?

Roll the foam into a thin crease-free cylinder, pull the ear up and back, insert past the canal opening, and hold 20–30 seconds while it expands; let the cord rest at the front of the neck.

Is the Moldex 6900 OSHA compliant?

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

When should I buy uncorded instead?

For continuous all-day wear where plugs are not removed, the uncorded 6800 costs less and ships in a 200-pair box.

Do you stock a detectable corded plug?

Yes — the corded metal-detectable Moldex 6615 SparkPlugs for food, beverage, and pharma lines.

How many boxes do I need?

Plan one pair per worker per shift; a 100-pair box covers a 25-person crew for about four shifts.

Does WC Safety stock the matching dispenser?

Yes — the Moldex 6882 Pura-Fit PlugStation Corded dispenses the 6900.
