1/8 NPT 4-jaw grease nipple coupling adapter for grease pump pipe

General Description: The 1/8 NPT 4-jaw grease coupling is a universal lubrication accessory that ensures a strong and stable connection during lubrication. The self-locking 4-jaw design prevents the connection from loosening under high-pressure lubrication, ensuring continuous and reliable operation with minimal grease loss. Thanks to the standard 1/8 NPT thread, it fits most grease fittings on the market. Specifications: Thread Type: 1/8 NPT; Material: High-strength carbon steel; Finish: Zinc-plated, rust and corrosion resistant; Integrated spring for high-pressure resistance. Application: To remove the coupling, gently twist and loosen the rear end slightly to reduce pressure on the jaws. Then pull the coupling firmly out. Be careful not to loosen the coupling too far, as the parts may come apart and be difficult to reassemble. Other Information: Product quality is checked at the factory before packaging. Therefore, small amounts of grease may remain on the packaging.
