Frequently asked questions
What is the difference between NPT and SAE ORB threads?
NPT (National Pipe Tapered) seals via thread interference and requires PTFE tape or sealant — leakage risk increases over time. SAE ORB (O-Ring Boss) has a straight thread and seals via an elastomeric O-ring against a machined face, providing a reusable, leak-free seal more suitable for hydraulic systems.
Can you supply NPT-to-metric or NPT-to-BSP cross-thread adapters?
Yes. We manufacture a full range of cross-standard adapters: NPT × Metric, NPT × BSPP, NPT × BSPT, NPT × SAE ORB, and more. Custom combinations are available with OEM manufacturing.
