White polypropylene union tee for 5/16 in tubing

This white polypropylene union tee connects three lengths of 5/16 in tubing in a T configuration for fluid distribution. The pack contains 10 fittings suitable for plumbing, food-service and drinking-water installations. Each piece meets NSF-51 and NSF-61 standards and complies with FDA requirements for food and beverage contact. The material withstands temperatures from 9 to 150 degrees F.

Rated for 150 psi continuous service pressure

The fitting maintains its seal at up to 150 psi during sustained operation rather than only in brief pressure spikes. Polypropylene construction resists creep and stress relaxation over long periods under load. NSF-51 and NSF-61 certifications confirm performance for potable-water and food-contact duties across the full temperature range. The white colour allows visual inspection for deposits or discoloration.

Verify tube size and chemical compatibility before

Ensure the existing system uses 5/16 in outside-diameter tubing so the push-to-connect ends seat correctly. Confirm that the fluid chemistry is compatible with polypropylene across the 9 to 150 degrees F range. Check that the 150 psi pressure rating exceeds the maximum operating pressure of the circuit. The pack quantity of 10 may exceed the needs of a single repair.

Questions about this item

Will the white polypropylene tee soften or leak if hot water runs through it all day?

The fitting is rated for continuous use up to 150 °F, well above typical household hot-water temperatures, so it will not soften or leak under normal daily operation.

What tubing must I already have for these 5/16 in tees to seal properly?

You need 5/16 in outside-diameter tubing — either polyethylene, nylon or soft copper — that matches the push-fit connection type of these union tees.

Can I mix these NSF-51 and NSF-61 approved tees with older brass compression fittings on the same line?

Yes, the 5/16 in push-fit ends connect directly to tubing, so you can transition to legacy brass compression fittings with a short length of compatible tube between them.
