Dixon 4AGF4 1/2in FNPTF x 1/2in Ag Interchange Ball Valve Socket Coupling 2PK

This listing is for two (2) new Dixon Valve 4AGF4 (model 18-400) AG-Series female socket hydraulic quick-disconnect couplings, both clearly marked "DIXON 18-400" in the photos along with individual date/batch codes (14SU and 13UT). The 4AGF4 part number decodes as follows: "4" = 1/2 in. body size (AG-Series size 4), "AG" = Agricultural Interchange series (ISO 5675 / SAE J1507), "F" = female NPT port, "4" = 1/2 in. port size (NPTF), making each coupling a 1/2 in. FNPTF inlet × 1/2 in. Agricultural Interchange ball-valve socket. The AG-Series is designed to mate with standard agricultural interchange nipples used on tractors, implements, and skid steers; the internal poppet/ball-valve mechanism allows single-end shutoff and is visible in the end-on photo showing the poppet and steel ball retainer. Bodies are carbon steel with a zinc/chromate finish for corrosion resistance, and seals are Nitrile (Buna-N), suitable for petroleum-based hydraulic fluid, making these couplings compatible with standard tractor hydraulic systems operating to 2,500 PSI working pressure.
