Brass Compression Extender Tee

The Value Brass Compression Supply Stop Extender Tee provides a 3/8 in by 1/4 in compression connection for plumbing supply lines. It suits installers who need a compact tee to branch a fixture supply from an existing stop valve. The brass body resists corrosion in potable water applications. This fitting is intended for new installations where a supply stop extender is required.

Compression Build and Hex Profile

The fitting uses a compression connection type that seals without soldering, allowing quick assembly with standard wrenches. A 5/8 in hex size gives a secure grip during tightening and reduces the risk of rounding corners. Brass construction provides durability and compatibility with copper or plastic tubing. The design meets typical residential plumbing demands for supply stop extensions.

Upgrade From Soldered Tees

This extender tee replaces soldered or threaded branch fittings where a compression joint speeds up service work. The jump is worthwhile when retrofitting supply stops without draining the entire system or using open flame. It is not suited for high-pressure hydronic loops or gas piping. Buyers needing larger branch sizes or different connection types should select an alternative fitting.

Questions about this item

What does the 3/8 in x 1/4 in compression interface cap in practice?

The tee connects a 3/8 in supply line to a 1/4 in outlet using compression nuts and ferrules, so the joint is sealed by tightening rather than soldering or threading.

What physical clearance does the 5/8 in hex need to fit or mount?

A 5/8 in open-end or adjustable wrench is required to engage the hex body; allow enough space around the fitting for the wrench swing and for the tube insertion depth on both ports.

How is this extender tee installed, and what step do people get wrong?

Slide the nut then ferrule onto each tube, insert tubes fully into the tee ports, hand-tighten both nuts, then finish with a wrench; the common error is not pushing the tube all the way home before tightening.
