Union (O-Ring Type), Slip x FPT PVC Schedule 80 1-1/2" (899-015)
$24.83
The 899-015 is a 1-1/2" Schedule 80 PVC Union with an O-ring seal, featuring a Slip socket inlet and Female Pipe Thread (FPT) outlet. Unions are an essential component in any pressure piping system where periodic disassembly is required — whether for equipment maintenance, valve replacement, pump service, or system modifications — without the need to cut or disturb the surrounding pipe.
The O-ring design provides a superior pressure seal compared to traditional flat-faced unions, relying on a compression-seated elastomeric O-ring rather than a solvent-welded or threaded face contact alone. This results in a more reliable, leak-resistant connection under both sustained pressure and thermal cycling conditions. The Slip x FPT configuration offers installation flexibility: the slip side accepts solvent cement for a permanent pipe connection, while the FPT end threads directly onto a male-threaded fitting, valve, or equipment port.
Manufactured from rigid PVC compound, this union meets Schedule 80 wall thickness standards and is rated for higher pressures than Schedule 40 fittings of equivalent size — making it the preferred choice in chemical processing, water treatment, irrigation infrastructure, and industrial fluid handling applications where system integrity and long service life are non-negotiable.
