Brass Push>Connect Metric Tube Fitting, 10.00 mm Tube OD To 3/8-19 Male Universal BSPP/BSPT, Straight

For that combo, it matches up: the push to connect side is for 10.00 mm tube OD, and the threaded end is 3/8-19 male universal BSPP/BSPT in a straight swivel adapter.

For standard compressed air instrumentation circuits, 250 psi is a solid working pressure ceiling, and most shop air and instrumentation lines run well below that. The vacuum rating sits at 29.5 inches of mercury, so low-pressure suction-side applications are covered too. The Buna-N O-ring seal holds up through continuous use across a wide temperature swing, from -40F all the way up to 200F. Just make sure the tubing itself is rated for whatever temperature range your line sees, because the fitting and the tube need to match up on that front.
