Perfect Match for KTR Coupling

These inserts fit my GR38 coupling exactly. The material feels robust and the vibration damping is excellent.

Good Value Alternative

Slightly harder than the original OEM parts but works fine for our application. Good price point.

Solid Industrial Build

Good quality rubber. Packaging was secure. One insert had a minor mold mark but did not affect performance.
