Buying Guide

Match the ISO standard

Confirm whether your system uses ISO5675 or ISO16028 couplers—mating parts must share the same standard to ensure proper sealing and function

Pick the correct thread/size

Select the right nominal size and thread (3/8" or 3/4" NPT/Ag) to ensure compatibility with hoses and ports and to avoid leaks or pressure loss

Choose poppet vs. non-poppet valves

Poppet-style quick-disconnects are common for positive shutoff and minimal fluid loss; plain couplers may be simpler but can allow more spillage during disconnect

Check pressure and flow specs

Verify the coupling’s rated working pressure and flow capacity against your hydraulic circuit to prevent premature wear or failure

Consider material and build quality

Look for rugged materials and quality finishes suitable for your environment—durability matters for undercarriage and construction use
