2 Sets Of 1/2" Npt Hydraulic Quick Connect Couplings With Dust Caps That Are Gute A1 Series is a general purpose, double shut-off quick coupling capable of containing a wide variety of fluids. This Series can be found anywhere a dependable connection and disconnection of a fluid transfer line is required. Rugged construction and low pressure drop make this series ideal for a variety of applications including plant maintenance equipment, skid steer loaders, snow plows, mining, dump trucks, gooseneck trailers and chemical transfer lines. This part GT-A1-04T-SP-NPT12 is one of the most popular one in this series. This size is so popular in lots of applications. Meets dimensional requirements of ISO7241-1 series A A general purpose, fluid transfer quick coupling that provides higher burst pressure and superior flow to that of Aerquip FD56 (5600) series and parker 6600 series, while providing half-for-half interchangeability. Interchangeability: Gute: Female: GT-A1-04T-S-NPT12 Male: GT-A1-04T-P-NPT12 Safeway: Female: S565-4 Male: S561-4 Parker: Female: 6601-8-10 Male:6602-8-10 Faster: Female:NV 12 NPT F Male:NV 12 NPT M Eaton: Female:FD56-1064-08-10 Male:FD56-1062-08-10 All quick coupling are 100% leak tested. Ideal for minimal space applications. The quick coupling uses solid steel barstock in its valving and retainers; no powdered metal parts. A higher number of detent (locking) balls and a specially hardened male tip (nipple) add to the overall integrity of the product and its higher rated working pressure. unique poppet/seat design allows no extrusion gap, minimizing seal degradation under extreme pressures. Stainless steel valve springs and retainer rings are standard. Feartures: Poppet valves available to prevent uncoupled leakage Poppet valves open autom The GT-A1 Series are widely used in industries, use on construction equipment, forestry equipment, oil tools, gas industries, steel mill machinery and other demanding hydraulic applications. Ball-locking Structure make this GT-A1 series connect or disconnect super quickly, stable and reliable. Poppet Valves - super good performance on prevent uncoupled leakage. When the coupling disconnects, the poppet valves disconnect and stop liquid leakage. Carbon Steel Material can work at a pressure at 27.6 Mpa, and designed a high flow of 45.5 L/min, the material are hardened for durability. Compatible with Parker hydraulic quick coupling 6600 Series, Faster hydraulic quick coupling ANV Series, Aeroquip 5600 Series and Hansen HA 15000 Series
