The VALUE COLLECTION 6630-203 is a push-to-connect tube-to-female NPT tube fitting designed for fast, tool-free connections in fluid-handling systems. Constructed from lead-free brass, it accepts 1/2-inch OD tubing on both tube ports and features a 1/2-inch female NPT center connection. The fitting is rated to 200 psi maximum working pressure and uses an EPDM O-ring to maintain a reliable seal. This type of fitting is commonly installed by plumbers and HVAC technicians where a quick-connect transition between tubing runs and threaded pipe is required without soldering or compression tools.
This fitting is suited for residential and light commercial plumbing, water supply, and HVAC applications where 1/2-inch OD tubing interfaces with a 1/2-inch female NPT threaded port. The push-to-connect design allows tubing to be inserted and locked in place without additional fittings or adhesives, making it practical for tight spaces or retrofit installations where torch work is not an option. It is appropriate for use with compatible rigid or semi-rigid tubing within the rated pressure range.
Designed as an OEM-style replacement or new-installation fitting for plumbing and HVAC systems using 1/2-inch OD tubing with 1/2-inch female NPT threaded connections.
Installation should be performed by a licensed plumber or qualified HVAC technician in accordance with applicable local codes and IPC guidelines. Shut off the water supply and relieve system pressure before servicing any fittings. Ensure tubing ends are cut cleanly and deburred before inserting into the push-to-connect port to maintain a proper seal. Do not exceed the 200 psi maximum working pressure rating for this fitting.
