Replacement Felt and O-rings | Sumo | DonnyFL – Air rifle maintenance kit

This maintenance kit contains four felt sheets and matching O-rings for servicing DonnyFL Sumo suppressors. The felt material captures particles and dampens sound in air rifles, while the black O-rings ensure airtight seals between components.

Construction and materials

The kit includes four pieces of felt and corresponding O-rings for a complete service. The black felt is specifically designed for DonnyFL Sumo suppressors. Each felt sheet acts as both a particle filter and sound dampening element within the suppressor's internal structure.

Application and use

This replacement foam kit is used for routine suppressor maintenance on air rifles. The felt material gradually becomes saturated with particles and residue during normal use, requiring periodic replacement to maintain optimal sound reduction and performance.

Integration and compatibility

These components are designed exclusively for DonnyFL Sumo suppressors. The felt sheets fit the internal dimensions of the Sumo model, while the O-rings match the specific threading and seal points. Always follow DonnyFL's disassembly instructions when replacing these parts.

Maintenance and lifecycle

Regular felt replacement extends suppressor lifespan and maintains consistent performance. Replace both felt and O-rings simultaneously to prevent air leakage. Replacement frequency depends on usage intensity, but inspection every few months helps determine when new felt is needed.
