Male Adapter, MPT x Slip PVC Schedule 80 3" (836-030)

The 836-030 is a 3" PVC Schedule 80 male adapter with a male pipe thread (MPT) inlet and a slip (socket) outlet, designed to transition a male-threaded PVC pipe end or fitting into a solvent-welded socket connection. The MPT inlet threads directly into any standard 3" female pipe thread (FPT) port — on a valve, pump, equipment nozzle, or threaded fitting — while the slip outlet accepts a standard 3" PVC pipe end joined with solvent cement and primer per ASTM D2564, continuing the pipeline as a permanent, pressure-rated solvent-welded run.

Manufactured from rigid, dark gray PVC compound conforming to ASTM D1784 cell classification requirements, the Schedule 80 wall construction delivers higher pressure ratings and greater mechanical strength than Schedule 40 equivalents at the same pipe size. This makes the 836-030 the correct choice for high-pressure chemical lines, industrial process piping, and any Schedule 80 system where the transition point between a threaded port and a solvent-welded pipe run must maintain full Schedule 80 pressure integrity. PTFE thread tape or appropriate thread sealant should be applied to the MPT threads before assembly to ensure a leak-resistant seal at the threaded inlet.

The MPT x slip male adapter is among the most frequently used transition fittings in Schedule 80 PVC systems, serving as the standard connection method wherever a threaded equipment port, valve body, or threaded fitting must be tied into a solvent-welded pipe run. At the 3" size, this adapter is commonly found at pump discharge and suction connections, large valve outlets, strainer assemblies, and equipment nozzles where a 3" threaded port must transition cleanly to a solvent-welded distribution or process line. Unlike the female adapter (835-020), which accepts a male-threaded fitting at its outlet, the male adapter threads into a female port — making correct gender identification before ordering essential to avoid mismatches at the connection point.

Industries & Applications:

• Industrial Process Piping — Transitioning 3" female-threaded equipment ports, valve bodies, and pump connections into solvent-welded Schedule 80 pipe runs in high-pressure chemical distribution and process fluid systems
• Chemical Processing — Corrosion-resistant thread-to-slip transitions at vessel nozzles, chemical feed equipment, and pump assemblies in acid, caustic, and aggressive fluid service where all-PVC construction eliminates metal corrosion and galvanic compatibility concerns
• Municipal Water & Wastewater — Connecting 3" threaded pump flanges, valve outlets, and equipment ports to solvent-welded Schedule 80 distribution and process piping at pump stations and treatment facilities
• Irrigation & Agriculture — Transitioning threaded pump discharge and valve connections into solvent-welded 3" Schedule 80 mainline pipe runs in high-pressure large-scale irrigation systems
• HVAC & Mechanical — Connecting threaded mechanical equipment ports and valve bodies to solvent-welded Schedule 80 chilled water and condenser water pipe runs in commercial mechanical rooms
• Aquaculture & Water Treatment — Thread-to-slip transitions at pump connections, filter equipment nozzles, and valve assemblies in recirculating system piping where downstream runs are solvent-welded Schedule 80 PVC
