[Small size] This grease nipple is easy to use in tight spaces. Smooth retraction mechanism allows for one-handed operation. Once the grease nipple is locked onto the nipple, it remains open, freeing both hands to operate the grease tool. [Up to 10,000 PSI locking and sealing] Reinforced jaws and high-quality seals ensure long-lasting and stable performance and prevent leakage even at extreme pressures of 10,000 PSI. [Unique design] The extended grease nozzle provides access to recessed mechanical parts, allowing the grease nipple to be found in blind spots. [Robust and durable] Made of high-quality stainless steel, the grease nipple is durable and ideal for continuous use without breakage, leakage, twisting or typical wear. The springs work well and ensure smooth sliding throughout the life cycle. [Compatible with all grease tools and grease nozzles] Suitable for standard grease tools, including mini grease tools. It also fits all DIN and SAE grease nipples, simply replace the existing grease tool attachment.
