Value Collection 6630-303 Push-to-connect Tube Fitting

Product Description

The VALUE COLLECTION 6630-303 is a push-to-connect tube-to-tube fitting designed for quick, tool-free connections in fluid and gas distribution systems. Constructed from lead-free brass with an EPDM O-ring, it accepts 1/2-inch OD tubing on both ends and is rated to 200 psi maximum working pressure. The push-to-connect design seats tubing with a single insertion, creating a secure, leak-resistant joint without soldering, flaring, or compression fittings. Plumbers, HVAC technicians, and mechanical contractors use this fitting type in potable water, hydronic, and light pneumatic applications where fast, reliable connections are required.

This fitting is suited for residential and light commercial installations where 1/2-inch OD tubing runs are joined inline. Common applications include domestic water supply lines, radiant heating distribution, and mechanical room piping. The lead-free brass construction meets requirements for potable water contact. The EPDM O-ring provides chemical compatibility with water and a range of mild fluid media.

Installation Notes

Installation is performed by licensed plumbers or qualified mechanical contractors. Shut off and depressurize the supply line before making or breaking any connection. Ensure tubing ends are cut square, deburred, and clean before insertion to achieve a proper seal. Verify that the system fluid, pressure, and temperature conditions are within the published rating of the fitting before placing the system back into service.
