Frequently Asked Questions

What is the difference between ORB and NPT thread connections?

ORB uses an O-ring seal in a machined groove for leak-free connections, while NPT relies on tapered threads. ORB provides more reliable sealing for high-pressure hydraulic applications.

Can I use NPT adapters in high-pressure hydraulic systems?

How do I determine the correct thread size for my adapter?

Are your ORB to NPT adapters compatible with all hydraulic fluids?

Do you offer 90-degree ORB to NPT adapters for tight spaces?

What is the typical lead time for out-of-stock adapter sizes?

Can these adapters be used in mobile equipment applications?
