CB-1141 Threaded Hydraulic Quick Coupling – 316 Stainless + Brass Hybrid for High-Pressure Jacks
The CB-1141 quick coupler is designed for portable hydraulic jacks and high-pressure lifting systems. Featuring a 316 stainless steel body and a brass locking sleeve, it combines corrosion resistance with wear protection. The threaded locking mechanism ensures secure connections even in vibration-heavy environments, while the compact mating seal minimizes separation forces—allowing connection and disconnection under residual pressure up to 5000 PSI.
Key Features
• 316 stainless steel body for high-pressure and corrosive environments
• Brass locking sleeve to reduce galling and enhance durability
• Thread-to-connect structure prevents accidental disconnection
• Small-diameter mating seal enables low separation force
• Connect/disconnect at up to 5000 PSI residual pressure
• Fully interchangeable with Parker 1141 Series
