Brass Compression Tee for 3/8 in Tubing

This brass tee connects 3/8 in compression tubing to two male NPT threads in a single fitting. It is rated for both potable and non-potable water systems up to 125 psi and 160 Degrees F. The compact body measures 1 21/32 in overall length for tight installations.

Straightforward Compression Installation

Slide the nut and ferrule onto clean, round tubing before inserting fully into the fitting body. Hand-tighten the nut then finish with a wrench, typically one to two turns past finger-tight. Over-tightening can crush the ferrule or split the nut, causing leaks that require replacement of the compression components.

Verify Thread Sizes and Pressure Rating

Confirm the mating ports accept 11/16-20 male threads and that your system pressure does not exceed 125 psi. The 9/16-24 compression thread requires 3/8 in OD copper or plastic tubing designed for compression fittings. This fitting contains chemicals listed under California Proposition 65.

Questions about this item

How can I confirm the 993-020NL tee is sealed correctly after installation?

Pressurize the line to the 125 psi rating and inspect all three connections for leaks; the brass body and compression nut should hold without weeping at the 3/8 in tube or the MNPT threads.

What comes with the 993-020NL and what must I supply?

The tee includes the brass body, compression nut and ferrule for the 3/8 in tube side; you must provide the 3/8 in copper or plastic tube and the two male NPT fittings that thread into the 11/16-20 ports.

Which version of the 993-020NL should I choose for a 160 °F hot-water line?

The single listed model is rated to 160 °F and 125 psi, so it covers standard hot-water service; no alternate capacity or temperature version exists in this range.
