If you work with high-pressure hydraulic systems, this Summit HPC coupler set is built to handle the serious pressure you're dealing with. Rated for 10,000 PSI working pressure with a massive 40,000 PSI burst rating, these couplers are no joke - they're designed for heavy-duty applications like high-pressure jacks, hydraulic tools, torque equipment, and rescue tools where reliability is absolutely crucial. The 3/8-inch body size with 3/8-inch NPT threads makes them compatible with standard hydraulic systems, and they can handle flows up to 6 GPM. What's really handy is the true push/pull connection system that lets you connect and disconnect quickly without tools, plus the safety sleeve lock prevents accidental disconnects that could be dangerous in high-pressure situations. The slim profile and compact design mean they fit in tight spaces where bulkier couplers might not work. The female coupler measures 2.56 inches, the male nipple is 2.19 inches, and when connected they're 3.51 inches total length. They're made from hardened high-strength steel that provides long service life and durability under tough conditions, and they can handle temperatures from -15°F all the way up to 400°F. These directly replace Parker TC series couplers (TC-371 female and TC-372 male) and Eaton Aeroquip FD35 series (FD35-1000-06-06 set), so if you're familiar with those quality brands, you know what level of performance to expect. Whether you're in equipment maintenance, manufacturing, rescue services, or any field requiring reliable high-pressure hydraulic connections, this coupler set delivers the performance and safety features you need. The construction quality is professional grade, and the design focuses on both performance and user safety - exactly what you want when working with systems operating at these extreme pressures.
