Question by: Frank B on Jun 2, 2025, 11:47 AM
got a little 0.13 OD tube, will this straight push-in fitting actually match up with a 1/16 male NPT port?
Answer by: Customer Support on Jun 3, 2025, 2:13 PM
It is made to take 0.13 inch tube O.D. on the push-in side and it has 1/16 male NPT threads on the other end, in a straight connector.

Question by: Debbie S on Jul 20, 2025, 9:56 PM
Got some polyurethane tubing I need to connect to a 1/16 NPT male port, this the right fitting for that?
Answer by: Customer Support on Jul 22, 2025, 12:59 PM
For polyurethane tubing at 90 durometer or harder, yeah, this fitting is built exactly for that pairing. The tube OD it accepts is 0.13 inches, so just confirm your tubing matches that outside diameter before ordering. The male thread is 1/16 NPT, and there's pre-applied Teflon-based sealant already on those threads, so you won't need to mess with tape on assembly. Push the tube in until it bottoms out in the cavity and you're sealed up.

Tell us what you need and we'll get back to you.
