Hydraulic Quick Couplings / Threaded

Thread-Locked & Thread-To-Connect Series

Threaded couplers use a thread-locking mechanism to maintain a secure connection under pressure and vibration. The male nipple threads into the female coupler body, creating a positive mechanical lock that eliminates the risk of pull-out under high-pressure surges. Available in both thread-to-connect and thread-locked configurations for maximum application flexibility.
