Frequently Asked Questions
Can these fittings stop leaks permanently?
It depends on the application. DOT-grade brass and properly installed threaded or push-to-connect fittings can provide long-lasting, leak-free repairs on air and brake lines. Reusable hydraulic fittings are excellent temporary or permanent fixes for braided hoses when used within their rated pressure and with correct hose types. If a hose is severely damaged, full replacement is safer.
How do I pick the right size fitting for my hose?
Measure the hose inner diameter (ID) and outer diameter (OD) or check the hose spec. Match NPT thread size for threaded couplers (e.g., 1/4" NPT) or pick the push-to-connect fitting sized to your tube (1/8", 1/4", 3/8", 1/2"). For hydraulic fittings, use the manufacturer’s SAE size (#04, #06, #08) to ensure proper fit.
Are push-to-connect fittings reliable for high-pressure systems?
Push-to-connect fittings are reliable for many air and low-to-moderate pressure pneumatic systems, but they’re generally not intended for high-pressure hydraulic lines. For hydraulic applications, use fittings rated for the hose’s working pressure or screw-on reusable fittings designed for braided hoses.
