Motorola PMLN8363 Small Rubber Sleeve Replacements

Motorola PMLN8363 Small Replacement Rubber Sleeves – 25 Pack

Keep your Motorola earpieces comfortable, hygienic, and ready for everyday use with the Motorola PMLN8363 Small Replacement Rubber Sleeve Kit. This genuine Motorola accessory contains 25 small rubber sleeves designed specifically for the Motorola PMLN8337 one-wire single earbud.

The PMLN8363 sleeve fits over the PMLN8337 earbud to provide additional friction and help hold the earbud comfortably in place. It is an excellent choice for replacing lost, damaged, stretched, or worn sleeves without purchasing a complete new earpiece. The 25-pack is particularly useful for public-safety departments, commercial radio fleets, warehouses, schools, security teams, and other organizations that share or regularly maintain radio accessories.

Motorola offers these replacement sleeves in three sizes. The PMLN8363 is the small option; PMLN8364 is medium, and PMLN8365 is large. Motorola’s accessory catalogs identify all three sizes as compatible with the PMLN8337 earpiece. motorolasolutions.com

Motorola PMLN8363 Specifications

Important compatibility note

The PMLN8363 is a replacement sleeve only. It does not connect directly to a Motorola radio and does not contain a speaker, cable, microphone, push-to-talk button, or radio connector.

Radio compatibility is determined by the complete PMLN8337 earpiece, not by the PMLN8363 sleeve itself.

Radio Applications

When installed on a compatible PMLN8337 earpiece, the PMLN8363 may be used in systems involving select:

• Motorola APX N30 radios
• Motorola APX N50 radios
• Motorola APX N70 radios
• Motorola MOTOTRBO R7 radios
• Motorola MOTOTRBO Ion smart radios
• Motorola MXP600 radios
• Motorola MXP660 radios

Motorola’s APX accessory catalog lists the PMLN8337 for the APX N30, APX N50, and APX N70, while its professional-series and MXP catalogs identify the PMLN8363 as the small replacement sleeve for that earpiece. motorolasolutions.com

Always verify the complete earpiece and radio model before ordering.

What Is Included?

• 25 Motorola PMLN8363 small replacement rubber sleeves

The package does not include:

• Motorola PMLN8337 electronic earpiece
• Removable earhook
• Speaker or earbud electronics
• Audio cable
• Push-to-talk button
• Microphone
• Clothing clip
• Two-way radio

If the PMLN8337 cable, speaker, PTT, microphone, or radio connector is damaged, replace the complete earpiece rather than ordering only the PMLN8363 sleeves.

Why Replace Earbud Sleeves?

Rubber sleeves are exposed to perspiration, skin oils, dust, dirt, and repeated handling. Over time, a sleeve can stretch, become damaged, or no longer hold the earbud securely.

Replacing the sleeve can help:

• Restore a more secure fit
• Improve comfort during extended shifts
• Prevent the earbud from moving during physical activity
• Maintain a cleaner shared-accessory program
• Reduce the need to replace an otherwise functional earpiece
• Give individual users their own removable sleeve
• Extend the useful life of the PMLN8337 earpiece

The economical 25-pack is well suited to departments or businesses that maintain multiple earpieces.

PMLN8363 Size Alternatives

Select the sleeve size that provides a secure fit without causing unnecessary pressure.

The PMLN8364 and PMLN8365 are size alternatives, not upgraded or superseding products. If several people share the same earpiece type, stocking multiple sizes can help accommodate different users.

Comparable and Replacement Products

Motorola PMLN8364 Medium Rubber Sleeves

Choose the PMLN8364 when the small PMLN8363 sleeve feels loose or does not provide enough surface contact. It includes 25 medium sleeves for the PMLN8337.

Motorola PMLN8365 Large Rubber Sleeves

The PMLN8365 is the large-size alternative. It is recommended when additional contact and stability are required.

Motorola PMLN8337 Complete One-Wire Earbud

Choose a complete Motorola PMLN8337 one-wire earbud when the speaker, cable, connector, microphone, or push-to-talk assembly is damaged. The PMLN8363 should be ordered when only the small rubber sleeve requires replacement.

PMLN8363 Versus PMLN8068

The PMLN8363 should not be confused with the similarly sized PMLN8068.

These accessory families use different attachment designs and are not interchangeable. Confirm whether your earpiece requires a rubber sleeve or a replacement eartip before placing your order.

Easy Installation

1. Remove the worn sleeve from the PMLN8337 earbud.
2. Inspect the earbud for dirt, damage, or remaining rubber material.
3. Align the new PMLN8363 sleeve with the earbud.
4. Gently press the sleeve into position.
5. Confirm that the sleeve is fully seated before wearing the earpiece.
6. Test the fit and select a different size if necessary.

Do not use adhesives or sharp tools during installation.
