NewAge Industries (Southampton, PA) offers Newloc® push-to-connect fittings in acetal copolymer and brass. Both allow quick connections to rigid and semi-rigid tubing such as nylon, polypropylene, and polyethylene. Typical applications include pneumatic control systems, robotics, instrumentation, and chemical lines. The fittings offer leak-proof connections with no flow restrictions, as well as a full vacuum rating (29.9 in/Hg). The plastic (acetal) Newlocs are suitable for pneumatics, while the brass Newlocs handle temperatures up to 200 °F.
