        Frequently asked questions

        How to measure hydraulic fittings?

        As per your experience to determine the thread is tapered or parallel, then use the tools ID/OD calipers and Thread pitch gauge to check Specific threads and dimensions.

        Do hydraulic fittings need O-rings?

        Most all hydraulic fittings use o-ring seals or 37 degree bevels as sealing methods and should not require sealant. It still can be pipe thread, just be careful with the sealant so it doesn’t get inside the system.

        Why does my hydraulic fitting keep leaking?

        Missing or damaged O-ring, or over/under-torqued fittings can also cause leaks as the seal will not align properly. Over/under torquing can lead to damaged threads, which almost certainly leads to leaks.

        Should you use Teflon on hydraulic fittings?

        Teflon tape should not be used to seal certain hydraulic fittings, including: NPTF  which forms a secure mechanical seal by essentially crushing the entire thread form– another good reason not to disconnect and reconnect this type of fitting. Instead, replace it during maintenance.

        Can you over tighten hydraulic fittings?

        Over-tightening hydraulic fittings can lead to several problems. The most immediate problem is joint failure. When too much torque is applied, it puts too much stress on the joint, leading to cracks or deformation. This can compromise the integrity of the connection, leading to leaks or even complete fitting failure.
