Moldex 6420 Rockets Reusable Earplugs with Cloth Cord — NRR 27dB, Pocket-Pak, 50 Pairs

Moldex Rockets — NRR 27 dB Reusable Flanged Earplug, 7 Variants Including Metal Detectable & Camo

The Moldex Rockets is a NRR 27 dB reusable multi-use flanged earplug with the broadest variant selection in the Moldex reusable earplug line — available in seven configurations covering corded, uncorded, cloth cord, metal detectable, and camouflage print formats. The Rockets' triple-flange stem design creates an acoustic seal at the ear canal entrance without requiring foam compression or deep canal insertion — making them the practical choice for workers who move frequently between noisy and quiet areas and need to insert and remove earplugs multiple times per shift. Available as: 6400 uncorded, 6405 corded, 6415 metal detectable, 6420 cloth cord, 6480 camo uncorded, 6485 camo corded. For a softer, ultra-comfortable NRR 27 reusable alternative, see the Moldex Alphas.

Key Features

• Reusable flanged design — practical for frequent in/out of noise areas: The Rockets' triple-flange stem creates an acoustic seal without foam compression — workers insert by twisting the flange end into the canal entrance, and remove without retrieving expanded foam from deep in the canal. This makes Rockets significantly more practical than foam plugs for workers who remove hearing protection multiple times per shift to communicate, then re-enter the noise area. Foam plugs require a new pair each insertion cycle; Rockets are re-inserted from the same pair worn around the neck
• Metal detectable 6415 — same broad applicability as SparkPlugs in reusable format: The 6415 contains metal-detectable compound throughout the flange body — satisfying HACCP, BRC, and SQF food safety program requirements for detectable PPE at NRR 27. The only NRR 27 reusable metal-detectable earplug in the Moldex lineup
• Broadest variant selection in the Moldex reusable line: Seven configurations — uncorded, corded, cloth cord, metal detectable corded, bagged corded, camo uncorded, camo corded — address every cord preference, program constraint, and aesthetic requirement across facility types and worker populations
• Latex-free, PVC-free, and antimicrobial: Clean material formulation plus antimicrobial compound helps inhibit microbial growth on the earplug body during multi-shift use — relevant when workers pocket and re-use the same pair across a full work week
• Pocket Pak format: Each pair comes in a Pocket Pak case that workers carry in a pocket — keeping the earplug clean, accessible, and protected between uses without requiring a bag or separate storage

Rockets vs. Moldex Reusable Earplug Alternatives

OSHA Compliance

Moldex Rockets are rated under ANSI S3.19-1974 at NRR 27. Under OSHA 29 CFR 1910.95, Rockets are appropriate hearing protection for workers with TWA noise exposures from 85 dBA to approximately 100 dBA — effective attenuation 10 dB (OSHA 50% derating). OSHA 1910.95(i)(4) requires training on correct insertion of the flanged design: all three flanges must seat in the canal entrance to achieve the rated NRR.

Frequently Asked Questions

What is the NRR of Moldex Rockets?

NRR 27 dB. Effective attenuation: (27 – 7) × 0.5 = 10 dB (OSHA 50% derating). Adequate for environments up to ~100 dBA TWA.

Are Moldex Rockets reusable?

Yes — reusable multi-use earplugs. Wash with soap and water, air dry, inspect before each use. Replace when flanges stiffen, crack, or permanently deform.

How do Rockets work?

Triple-flange stem sits at the ear canal entrance — no deep insertion. Pull ear up and back, twist the flange end into the canal entrance until all flanges seat and a seal is felt. No foam compression required. Remove by gently rocking and pulling the stem.

What is the metal detectable Rockets 6415?

Corded NRR 27 Rockets with metal-detectable compound embedded in the flange material — for food processing and pharmaceutical facilities with metal detection or X-ray inspection requirements (HACCP, BRC, SQF compliance).

Are Moldex Rockets latex-free?

Yes — latex-free, PVC-free, diisocyanate-free, and antimicrobial. Appropriate for latex-sensitive workers and most food-grade programs.

How do Rockets compare to Alphas?

Both are NRR 27 reusable Moldex earplugs. Rockets have the widest variant selection (7 options including metal detectable and camo). Alphas use ultra-soft material and a 3-position wearing design for maximum comfort. Both are flanged reusable — choose based on which additional feature matters most to your program.
