Value Collection 6630-304 Push-to-connect Tube Fitting

Product Description

The VALUE COLLECTION 6630-304 is a push-to-connect tube-to-tube fitting designed for fast, tool-free connections in plumbing and fluid-handling systems. Constructed from lead-free brass with an EPDM O-ring, it accepts 3/4-inch OD tubing and is rated for up to 200 psi working pressure. The push-to-connect design allows a technician to make a secure, leak-resistant joint by simply inserting the tube end — no soldering, threading, or compression nuts required. Licensed plumbers and HVAC technicians commonly use fittings of this type when working with copper or compatible plastic tubing in water supply, hydronic, or refrigeration line applications.

This fitting is suited for residential and light commercial installations where a quick-disconnect or permanent inline tube joint is needed. The tube-to-tube configuration makes it a straight union for joining two sections of 3/4-inch OD tubing within the same run. Its lead-free brass construction satisfies potable water compliance requirements, making it appropriate for domestic water systems as well as non-potable fluid lines. The EPDM O-ring provides reliable sealing across a range of fluid types and temperature conditions typical of indoor mechanical systems.

Key Features

• Push-to-connect design — no solder, threads, or compression tools required for installation
• Lead-free brass construction meets potable water compliance standards
• Rated to 200 psi maximum working pressure
• EPDM O-ring for durable, leak-resistant sealing
• Tube-to-tube (union) configuration for inline 3/4-inch OD tubing connections

Compatibility

Designed as an OEM-style replacement or new-installation fitting for systems using 3/4-inch OD tubing in plumbing, HVAC, or fluid-transfer applications.

Installation Notes

Installation is performed by a licensed plumber or qualified HVAC technician. Shut off the water supply and relieve system pressure before making or breaking any fitting connection. Ensure tube ends are cut square, deburred, and clean before insertion to achieve a proper seal. Verify that the tubing material and diameter are fully compatible with push-to-connect fittings before installation per applicable IPC or local plumbing code requirements.
