Value Brand 993-018NL 1/2" x 3/8" Compression Brass Supply Stop Extender Tee

SKU CH-KSBS-C2J85

Brass compression tee extends a 1/2" supply stop to 3/8" tube at 125 psi

  • Compression fitting installs quickly without soldering
  • Brass construction resists corrosion for long service life
  • NSF 61 and NSF 372 certified for safe drinking water
  • Rated to 125 psi for reliable household pressure
  • California Proposition 65 notice included for chemical awareness

Supply Stop Extender Tee

This brass compression fitting extends a 1/2 inch supply stop while adding a 3/8 inch branch. It suits installers who need an extra outlet without replacing the existing valve. The tee meets ASME A 118.12.1 and carries NSF 61/NSF 372 approval for potable water. It is not for gas lines or buyers who need a different pipe size or thread type.

Thermals and pressure rating

The fitting handles a maximum pressure of 125 psi across a temperature range of 32 degrees to 210 degrees F. Brass construction resists corrosion in normal water supply conditions. No moving parts mean silent operation and no power draw. The compression connection with 11/16 in -20 threads seals without soldering or specialised tools.

Sustained load behaviour

Under continuous pressure and temperature cycling the brass body maintains its seal without degradation. The hex size of 3/4 in allows secure tightening for long term reliability. California Proposition 65 warnings apply due to chemical content. The tee is restricted to water use only and is not suited for applications exceeding the rated pressure or temperature limits.

Questions about this item

How do I install the 1/2" compression tee without damaging the 11/16"-20 threads?

Slide the compression nut and ferrule onto the 1/2" pipe, seat the tee squarely, then tighten the nut to the 3/4" hex with a wrench; over-torquing the 11/16"-20 compression threads is the common error that causes leaks.

Which component will need replacement first on a potable-water line?

The brass compression ferrule on the 3/8" outlet typically deforms after repeated disassembly; the tee body itself is NSF 61/372 approved for continuous water use and does not require scheduled replacement.

At what pressure will the fitting reach its rated limit during sustained flow?

The maximum working pressure is 125 psi; exceeding this value under constant temperature conditions is the first limit encountered in service.
