Product Questions & Answers (2)

Question by: Steve P on Nov 1, 2025, 4:59 PM
What size threads does this adapter use? I need to make sure it'll fit my setup.
Answer by: Customer Support on Nov 3, 2025, 6:48 AM
This steel adapter uses 1-1/2-11-1/2 Male NPT on one end and 3/8-18 Female NPT on the other. Those sizes should allow a secure connection in various industrial applications.
Question by: Wayne B on Aug 16, 2025, 7:19 AM
does this bushing need any thread sealant or tape when you put it together, or is it good to go as-is?
Answer by: Customer Support on Aug 17, 2025, 12:17 PM
No sealant needed on this one. The NPT threads are self-sealing by design, so you can install it straight out of the box without tape or compound. That cuts down on prep time and keeps things clean around the fitting.
