Product Description

Upgrade or replace your HK USP .40 cal barrel O-rings with this 2-pack of Viton replacement O-rings, the OEM-equivalent for Heckler & Koch part #987141.

Designed specifically for USP Tactical, USP Expert, USP Elite, and VP9L .40 barrels featuring factory O-ring grooves, these O-rings are critical for maintaining proper barrel fit, consistent slide lockup, and overall reliability.

Crafted from high-performance Viton, these rings are engineered to be heat-resistant, oil-resistant, and solvent-resistant. They won't swell or degrade under the high temperatures of rapid fire or during deep cleaning with aggressive chemicals. Whether you are performing routine maintenance or building a "go-bag" spare parts kit, these are essential for any HK .40 owner.
