Male Adapter, MPT x Slip PVC Schedule 80 1" (836-010)

This 1" Schedule 80 PVC Male Adapter provides a permanent, pressure-rated transition from a solvent-cemented PVC pipe system to a 1" male NPT threaded connection, enabling a Schedule 80 PVC pipe run to interface directly with female-threaded valves, pumps, equipment ports, strainer bodies, flow meters, and threaded couplings. The slip socket end accepts standard 1" PVC pipe for solvent cement joining, while the MPT end threads into any compatible 1" FPT port without additional adapters.

At 1", this adapter operates at one of the most common threaded interface sizes in commercial and industrial piping. The prevalence of 1" NPT ports across standard valves, pump bodies, instrumentation, and process equipment means the 836-010 sees regular use across a wide range of system types — from mechanical room plumbing to chemical process headers — wherever a solvent-welded PVC run must terminate at a female-threaded component. It is among the most frequently stocked fittings in any Schedule 80 installation or field repair inventory.

As with all male adapters, the 836-010 presents an MPT end that inserts into female-threaded ports — the inverse of a female adapter, which receives male-threaded components. The distinction matters in the field: when the receiving port is female-threaded (FPT), the male adapter is the correct selection. When the upstream piping must receive an externally threaded nipple or fitting, the Schedule 80 female adapter (835-series) is the appropriate counterpart. The two adapters are frequently used together at flanged valve assemblies, union transitions, and equipment connections where both sides of a threaded interface require a socket-to-thread conversion.

Manufactured in dark gray Schedule 80 PVC, this adapter delivers the increased wall thickness and mechanical strength required in industrial, chemical, and commercial pressure piping where Schedule 40 ratings are insufficient. PVC's broad chemical resistance profile covers acids, bases, salts, chlorine, and most common process fluids, providing long service life in corrosive environments where metal adapters would corrode, seize on threads, or introduce contamination into the fluid stream. NSF/ANSI 61 listing confirms suitability for potable water contact.

Rated to 450 psi at 73°F, this fitting handles standard to elevated pressure service across a wide range of fluid handling applications. For the slip socket end, clean and dry the pipe end and socket interior before application. Apply purple PVC primer to both mating surfaces, then apply a uniform coat of Schedule 80 PVC solvent cement to both surfaces before inserting the pipe. Hold with a slight quarter-turn twist for 30 seconds and allow full cure time per the cement manufacturer's temperature and humidity guidelines before pressurizing. Apply PTFE tape or compatible thread sealant to the MPT threads before engaging any female-threaded port. Hand-tighten plus one to two turns — avoid over-torquing into PVC female threads, as excessive force risks cracking the receiving fitting. Apply published pressure derating factors for service temperatures above 73°F.

Industries & Applications:

• Industrial Process Piping — Terminates a 1" Schedule 80 PVC solvent-welded process line at a female-threaded gate valve, ball valve, check valve, strainer, or flow meter in chemical processing, water treatment, and manufacturing facility piping; a high-frequency adapter in any Schedule 80 process system given the prevalence of 1" NPT equipment ports across standard industrial components
• Commercial Plumbing — Connects solvent-cemented 1" Schedule 80 PVC pipe runs to female-threaded shutoff valves, pressure gauges, backflow preventer inlets, and equipment connections in mechanical rooms, utility chases, and building water distribution systems requiring Schedule 80 pressure performance
• Water & Wastewater Treatment — Provides a slip-to-MPT transition at female-threaded pump flanges, filter vessel inlets, chemical dosing equipment ports, and process instrument connections along 1" Schedule 80 PVC headers in municipal and industrial water treatment facilities
• Chemical Handling — Delivers a corrosion-resistant solvent-cement-to-male-thread transition at tank outlet valves, reagent distribution headers, chemical injection equipment, and recirculation loop connections in systems handling acids, caustics, fertilizer solutions, and other aggressive fluids where metal adapters would degrade
• Irrigation & Agricultural Systems — Connects 1" Schedule 80 PVC pressure mains and laterals to female-threaded control valves, filter housings, fertigation injectors, pressure regulators, and pump discharge ports in high-pressure commercial irrigation, greenhouse, and agricultural water supply systems
• HVAC & Mechanical Systems — Used in PVC cooling tower makeup lines, glycol distribution systems, treated water headers, and chilled water drain piping where a 1" Schedule 80 slip-to-MPT adapter provides a schedule-consistent, corrosion-resistant pipe-to-equipment thread transition at female-ported mechanical components
