Q/R #4 Str Male Socket Push to lock Hose Barb

The JIFFY-TITE Q/R #4 Straight Male Socket Push-to-Lock Hose Barb (MPN 21504P) is a quick-release hydraulic coupling designed for AN-4 hose connections in fluid transfer systems. This product is ideal for users in various industries, including agriculture and construction, who require reliable and efficient hydraulic connections.

This straight adapter features a valved male socket configuration with an FKM elastomer seal, engineered to prevent fluid spillage during coupling and uncoupling operations. The aluminum body with a black and gold anodized finish provides corrosion resistance, making it suitable for demanding environments. The push-to-lock design allows for rapid disconnection without tools or residual pressure bleed-off delays.

Users maintaining or assembling mobile hydraulic systems—including agricultural machinery, construction equipment, and fluid-transfer operations—rely on JIFFY-TITE couplers for repeated connect-disconnect cycles without service interruption. The internal valve seals the female port immediately upon disconnection, minimizing spillage of hydraulic fluid and reducing environmental contamination.
