per EACH (USD)Adapter, 1/8" NPT Male to 5/32" Hose Barb, Stainless Steel
Converts a 1/8" NPT port to a 5/32" hose barb.
The Racetronix ADF-B18N532SS connects 5/32" ID rubber hose to a 1/8" NPT port. It is the stainless vacuum/boost port nipple used on Racetronix fuel pressure regulators, also sold as a replacement and for other small vacuum lines.
Key features
- 1/8"-27 NPT male.
- 5/32" hose barb for rubber hose.
- 304 stainless steel.
The NPT thread is tapered and seals on its threads: use a fuel-safe thread sealant (PTFE paste) on the male NPT threads, keeping it off the first thread. Push the hose fully over the barb and secure it with a suitable hose clamp.
