Buying Guide

Match the coupling standard

Choose couplings that match your system standard (ISO 5675, ISO 16028, ISO 7241-B, NPT) to ensure compatible mating with existing hoses and fittings

Pick the right face style

Decide between poppet (common, compact) and flat-face (reduced spillage, easier connect under pressure) based on leak control and equipment type

Check thread and bore size

Confirm NPT or metric thread sizes and internal bore (3/8, 1/2, 3/4) to maintain flow rates and avoid pressure drops or cavitation

Prefer durable materials

Select steel or plated steel constructions for high-pressure, mobile, and abrasive environments; look for corrosion-resistant finishes if exposed to weather

Consider skid-steer and high-flow needs

For skid-steer or high-flow applications choose larger-diameter, high-flow couplers and flat-face designs to minimize turbulence and heat
