Male Adapter, MPT x Slip PVC Schedule 80 2" (836-020)

The 836-020 is a 2" PVC Schedule 80 male adapter in an MPT x slip (male pipe thread x socket) configuration. The slip end accepts 2" plain-end pipe for solvent welding, while the male-threaded end connects directly into any compatible female-threaded (FPT) fitting, valve, equipment port, or threaded union half — making this a clean, single-fitting solution for transitioning between a solvent-weld pipe system and a threaded connection point.

The male adapter is one of the most fundamental transition fittings in PVC pressure piping, and the 2" size is among the most frequently specified. It appears wherever a solvent-weld distribution system needs to connect to a threaded valve, a pump port, a strainer, a union, or any piece of equipment with a female-threaded inlet. The MPT end threads directly into the receiving FPT connection, while the slip end becomes a permanent part of the surrounding solvent-weld pipe system — creating a transition point that is fixed on the pipe side and accessible on the threaded side for future equipment changes or system modifications.

The Schedule 80 construction of the 836-020 is an important distinction from its Schedule 40 counterpart. The heavier wall thickness provides meaningfully higher pressure ratings and greater resistance to mechanical stress at the threaded engagement — a relevant consideration at a transition point where the fitting may be subject to torque during assembly, thermal expansion forces from temperature cycling, or vibration from connected equipment such as pumps and valves.

Built from rigid PVC compound to Schedule 80 dimensional standards, the 836-020 is fully resistant to corrosion, chemical attack, and biological fouling — with none of the rust, thread seizure, or galvanic concerns that accompany metal transition fittings in wet or chemical service environments. Thread sealant should be applied at the MPT end to ensure a leak-free connection under operating pressure.
