Product Questions & Answers

Does this adapter go straight from ORB to NPT without needing any sealant on the threads?
Question by: Lyle G on Jul 2, 2025, 7:59 AM
The SAE O-Ring Boss side handles sealing through the O-ring itself, so no thread sealant is needed on that end. The male NPT side follows standard tapered pipe thread practice, which typically relies on the thread engagement to form a mechanical connection. Because both ends are male, this adapter is meant to bridge an ORB port on one component to an NPT female port on the other, keeping the assembly clean and straightforward.

So, this adapter... it'll let me hook up a SAE O-ring to a NPT pipe, right? Just wanna make sure I'm understanding it correctly.

Functionally, yes, it adapts a 1-5/16-12 Male SAE O-Ring Boss (Straight Thread O-Ring) connection to a 1-11-1/2 Male NPT connection. It's a straight adapter, not an angled one.
