About This Item:
Get a secure, accurate connection to standard grease fittings with the Pressol Precision Grease Coupler. Its four hardened spring-steel jaws grip the fitting firmly, helping deliver grease exactly where it is needed while minimizing slipping and leakage.
The compact 0.59-inch body reaches lubrication points where larger couplers may be difficult to position. A corrosion-resistant galvanized steel finish and precision-built construction make it a dependable replacement coupler for grease guns used in automotive, agricultural, construction, fleet and industrial maintenance.
The 1/8-inch female NPT connection fits grease-gun hoses and rigid extensions equipped with a matching male NPT thread.
