The L-800BP is a hydraulic coupler designed to connect a grease gun hose to a grease nipple quickly and securely, with a positive locking mechanism that prevents disconnection under pressure. The coupler clicks onto the nipple head and locks in place — eliminating the slipping and grease blowback that occurs with a standard push-fit coupler when nipple access is awkward or the gun is at an angle.

Compatible with standard straight and button-head grease nipples. Suits the L-450 lever grease gun and most professional-grade grease guns with a standard hose fitting. A practical upgrade for operators working in tight spaces or on nipples that are difficult to hold a standard coupler against.
