Coupling, Slip PVC Schedule 80 1-1/4" x 3/4" (829-167)
$8.19
The 829-167 is a PVC Schedule 80 reducing slip coupling designed to connect a 1-1/4" pipe run to a 3/4" pipe run using solvent-weld socket ends on both sides. Schedule 80's thicker wall construction provides higher pressure ratings and greater mechanical strength compared to Schedule 40, making this coupling a reliable choice where elevated pressures, industrial chemical exposure, or demanding service conditions are present.
The slip (socket) end configuration allows for straightforward solvent cement installation — no threads to tape or torque, just a clean, permanent bond that becomes integral to the piping system. Reducing couplings like the 829-167 are used wherever a flow path needs to step down in diameter in-line, whether for pressure management, equipment connection, or system design purposes.
Manufactured from rigid PVC Type I, Grade I (Cell Classification 12454) material, this fitting offers excellent corrosion resistance across a wide range of chemicals, acids, and bases. It is NSF/ANSI 61 listed for potable water contact and UV-resistant enough for indoor installation, though prolonged outdoor UV exposure without protective coating should be avoided.
