Description: Locking and Sealing to 12,000 PSI: Reinforced jaws and high-quality seals ensure long-lasting performance and prevent leaks even at extreme pressure of 12,000 PSI. Durable: Made of high-quality metal material, it can be used all day in the garage and is heavier and stronger than other fittings. Labor Saving Nozzle: Using a high pressure coupler to lubricate the joint or bearing provides improved precision, pressure and flow control in applying and delivering it to areas that would otherwise be difficult to access. Easy to use: Well designed to ensure pressure lubrication by pressing it into areas of the pivot bearing that may otherwise be very difficult to reach without disassembly. Wide Application: Can save time, avoid leaks and get rid of the daily frustrations that bad lubrication equipment brings. Widely used by mechanics, engineers and hobbyists alike.
