The VALUE COLLECTION 6630-005 is a push-to-connect tube-to-tube fitting manufactured from lead-free brass. It is designed for inline tube connections where a quick, tool-free join is required. The fitting accepts a 1 inch outside diameter tube and has a 1-1/8 inch thread size. With a 200 psi pressure rating and an EPDM O-ring seal, it is suited for general-purpose fluid handling in plumbing and HVAC piping systems. Licensed plumbers and pipefitters install this type of fitting during new construction and retrofit work where push-fit connections are specified.
This fitting is intended for general-purpose applications in residential and light commercial plumbing systems. It installs wherever a tube-to-tube push-to-connect joint is needed, including water supply lines and hydronic piping runs. Its lead-free brass construction meets NSF/ANSI 61 requirements for potable water contact, making it appropriate for domestic water systems. The compact overall length of 2.6 inches allows use in tight spaces where standard compression or solder fittings may be difficult to seat.
Designed as a general-purpose push-to-connect replacement fitting for tube-to-tube connections with a 1 inch outside diameter tube in potable water and general plumbing piping systems.
Installation is performed by licensed plumbers in accordance with the applicable International Plumbing Code (IPC) or local authority requirements. Shut off and depressurize the supply line fully before removing any existing fitting or cutting into a tube run. Ensure the tube end is cut square, deburred, and clean before inserting it into the push-to-connect collar to achieve a proper seal. Do not exceed the rated working pressure of 200 psi in service.
