Watts 0651130 Push-to-connect Male Connector 1 in Npt

Product Description

The WATTS 0651130 is a push-to-connect male connector tube fitting designed for fast, tool-free connections in fluid distribution systems. Constructed from brass with an EPDM O-ring, this fitting joins 1-inch OD tubing on each end to a 1-inch male NPT threaded port at center. The push-to-connect mechanism allows a technician to seat tubing with a single hand push, eliminating the need for compression sleeves or separate ferrules. It is suited for plumbing, HVAC hydronic distribution, and general fluid conveyance applications where a reliable, leak-tested transition between tube and NPT-threaded components is required.

This fitting is intended for residential and light commercial plumbing and hydronic piping installations. The tube-to-MNPT-to-tube configuration makes it a practical choice when connecting straight tubing runs to threaded valves, manifolds, or equipment ports. Licensed plumbers and pipefitters install this type of fitting during rough-in or system modification work where minimizing labor time on threaded connections is a priority.

Key Features

• Push-to-connect design on both tube ends for fast, tool-free installation
• 1-inch OD tube connection on each side with 1-inch male NPT center thread
• Brass body construction for corrosion resistance in fluid service
• EPDM O-ring seals rated for compatibility with a wide range of fluids
• NPT thread type for standard North American threaded port compatibility

Compatibility

Designed as an OEM-style replacement or new-installation fitting for plumbing and hydronic systems using 1-inch OD tubing and 1-inch NPT threaded connections.

Installation Notes

Installation should be performed by a licensed plumber or qualified pipefitter in accordance with applicable IPC or local plumbing codes. Shut off the water supply and depressurize the line before cutting into any existing piping. Ensure tubing ends are cut square, deburred, and cleaned before seating into the push-to-connect ports. Do not exceed the fitting's rated working pressure or temperature as specified by the manufacturer.
