Industrial B454-3 Quick Disconnect Coupling Nipple

The SNAP-TITE B454-3 1-1/4" Nipple is a high-pressure hydraulic quick-disconnect coupling nipple that provides secure, leak-resistant connections between fluid lines in industrial and mobile hydraulic systems. As part of the SNAP-TITE B Series, it uses a nipple (male quick coupling end) and offers thread options such as NPT/NPTF or system-specific end fittings, with variants in steel or stainless steel. It is rated for high-pressure hydraulic service (up to about 5,000–10,000 PSI depending on configuration), supports either full-flow or poppet-style operation, and employs an O-ring or poppet sealing system depending on the variant, with an operating temperature range aligned to industrial hydraulic fluids. Designed as an inline hydraulic coupling interface, it enables rapid coupling/decoupling for hydraulic machinery, construction equipment, and industrial fluid systems operating in heavy-duty environments, including manufacturing plants, heavy equipment, and fluid power systems; common replacements include Parker Snap-Tite 71 Series 1-1/4" coupling nipple, Stucchi hydraulic quick coupling nipple (1-1/4" class), and Faster (Aeroquip) high-pressure quick disconnect nipples.
