Moldex 6632 Meteors Small Review: Corded — 100-pair box NRR 28

Moldex 6632 Meteors Small Corded NRR 28 — Smaller Ear Canal Fit with Tether Cord for FOD-Mandate and Cord-Mandate Programs

The Moldex 6632 Meteors Small Corded combines the smaller-diameter bell-shaped foam of the Moldex 6630 Meteors Small with a tether cord — delivering the correct anatomical fit for narrow ear canals in facilities that mandate corded hearing protection for FOD-prevention or policy compliance. NRR 28. High-visibility lime. 100 pairs per box. Made in USA. This review covers the 6632's combined sizing and cord advantages, OSHA 29 CFR 1910.95 compliance, NRR 28 attenuation, and selection guidance within the Meteors family.

Editorial Verdict — 4.2 / 5

The Moldex 6632 is the corded small-diameter variant of Moldex Meteors — NRR 28, lime, bell-shaped, tethered. The only Moldex option for workers with narrow ear canals in cord-mandate facilities. For uncorded small, see Moldex 6630. For standard-diameter corded, see Moldex 6970.

Pros
  • Only Moldex corded option for narrow ear canal workers — fills a specific fit gap
  • NRR 28 — 10.5 dB(A) effective; covers up to ~100.5 dB(A) TWA single-protector
  • Tether cord prevents earplug loss into product streams or machinery
  • Bell-shaped foam — easier insertion in narrow canals vs. flat-ended cylindrical
  • High-visibility lime — confirms wear compliance from distance
  • Made in USA; NIOSH approved
Cons
  • NRR 28 — limited protection above ~100.5 dB(A) TWA single-protector
  • 100 pairs per box — higher per-pair cost than uncorded 200-pair box
  • Cord not metal-detectable — not suitable for food/pharma metal detection programs
  • Requires fit evaluation to confirm small size is anatomically indicated

Frequently Asked Questions: Moldex 6632 Meteors Small Corded NRR 28

Q: What is the NRR of the Moldex 6632 Meteors Small Corded?

A: The Moldex 6632 has an NRR of 28 dB. Per OSHA 50% derating, effective attenuation is approximately 10.5 dB(A), covering environments up to approximately 100.5 dB(A) TWA for single-protector compliance.

Q: What is the difference between the Moldex 6632 and Moldex 6630?

A: Both use the same NRR 28 small-diameter bell-shaped lime foam. The Moldex 6630 is uncorded (200 pairs/box); the Moldex 6632 adds a tether cord (100 pairs/box) for FOD-prevention and cord-mandate facilities.

Q: Is the Moldex 6632 cord metal-detectable?

A: No. The Moldex 6632 cord is not metal-detectable. For food processing or pharmaceutical programs requiring metal-detectable corded earplugs, use the Moldex 6615 SparkPlugs Metal Detectable Corded (note: standard diameter).

Q: Is the Moldex 6632 NIOSH approved?

A: Yes. The Moldex 6632 is NIOSH approved under 42 CFR Part 84 / 29 CFR 11.57.

Q: Are Moldex 6632 earplugs made in the USA?

A: Yes. The Moldex 6632 is manufactured in Covina, California.

Q: What is the Moldex 6632 suitable for that the Moldex 6970 is not?

A: The Moldex 6632 is specifically for workers with narrow ear canals in cord-mandate facilities. The Moldex 6970 Meteors Corded is the equivalent for standard ear canal anatomy, delivering NRR 33.

Q: How do I determine if a worker needs Moldex 6632 vs. 6970?

A: Start with the Moldex 6970 standard corded. If the worker cannot achieve adequate fit (plug works loose, user seal check shows inadequate occlusion), switch to the Moldex 6632 small corded. Document the fit evaluation.

Q: What OSHA standard covers hearing protection in cord-mandate facilities?

A: OSHA 29 CFR 1910.95 governs hearing conservation program requirements. Cord mandates are typically facility-specific FOD prevention policies rather than OSHA-mandated requirements. However, the employer's HCP must still ensure that required hearing protection (including corded options) provides adequate attenuation for the noise exposure levels present.

Q: Does the cord affect NRR or attenuation performance?

A: No. The cord does not affect the acoustic properties of the foam. The Moldex 6632 achieves the same NRR 28 as the uncorded Moldex 6630.

Q: How does the Moldex 6632 perform at 90 dB(A) TWA?

A: At 90 dB(A) TWA (OSHA PEL), the Moldex 6632 NRR 28, derated per OSHA 50%, reduces effective exposure to 79.5 dB(A) — well within compliance for an 8-hour TWA.

Q: What is the NIOSH derating for the Moldex 6632?

A: NIOSH recommends (NRR−7)/2 for foam earplugs: (28−7)/2 = 10.5 dB(A) effective. For exposures above approximately 95.5 dB(A) TWA, NIOSH guidance recommends dual protection even with a correctly-fitted Moldex 6632.

Q: What other Moldex corded earplugs should I compare to the 6632?

A: Compare the Moldex 6632 against: Moldex 6970 (NRR 33, standard, corded), Moldex 6622 (NRR 33, eco, corded), Moldex 6609 (NRR 33, camo, corded), and Moldex 6615 (NRR 33, metal-detectable, corded).

Q: Can I use Moldex 6632 for dual protection?

A: Yes. For environments above 100 dB(A) TWA, combine the Moldex 6632 with compatible earmuffs. Add 5 dB to the higher NRR value per OSHA guidance on dual protection.

Q: Why would a facility choose 6632 over 6630 for its workers?

A: If the facility has a FOD-prevention or cord-mandate policy, the Moldex 6632 is required for small-canal workers. Without a cord policy, the uncorded Moldex 6630 is lower cost-per-pair at 200 pairs/box.

Q: Where can I buy Moldex 6632 Meteors Small Corded earplugs?

A: The Moldex 6632 is available at WC Safety. Also on Check Price on Amazon →.

Q: Does the 6632 satisfy OSHA variety requirements for hearing protectors?

A: Offering the Moldex 6632 alongside standard-diameter options like the Moldex 6970 and Moldex 6608 Camo Plugs Uncorded helps satisfy OSHA 29 CFR 1910.95(i) variety requirements by providing fit options for different canal anatomies.
