Buying Guide

Match thread and tubing size

Confirm the fitting thread (for example 3/8-24) and tubing size (such as 3/16 in or 3/8 in) to ensure leak-free connections

Choose correct standard

Pick DOT- or SAE-rated fittings for brake or air systems to meet safety and compatibility requirements

Material matters

Use steel fittings for line adapters and brass for air-hose ends where corrosion resistance and malleability are important

Consider kit variety and counts

Select kits with the right mix and quantity of unions, tees, and quick-connects to avoid multiple purchases during repairs

Inspect protective features

Look for rubber-insulated clips and spring guards on hose ends to prevent chafing and protect fittings in service
