3/4" Flange (Solid Style) FPT PVC Schedule 80 (852-007)

The 852-007 is a 3/4-inch Schedule 80 PVC solid style flange with a female pipe thread (FPT) connection on the pipe end. Solid style construction means the flange face and body are manufactured as a single integral unit — the flange face does not rotate and is permanently fixed relative to the threaded bore, providing a rigid, stable mating surface for bolted flange assemblies where bolt hole alignment is set during installation.

The FPT pipe end accepts standard male NPT threaded pipe or fittings, making this flange straightforward to install into existing threaded piping systems without the need for solvent cement or specialized tooling. The flange face is drilled to the ANSI/ASME B16.5 Class 150 pattern — the industry-standard 4-bolt configuration at 3/4" size — ensuring compatibility with standard mating flanges, valve flanges, pump flanges, and equipment nozzles across manufacturers.

Schedule 80 PVC construction delivers the pressure ratings and wall thickness required for demanding industrial service, and gray PVC provides broad chemical resistance to acids, alkalis, salts, and many industrial process fluids. This fitting is manufactured from virgin PVC compound conforming to ASTM D1784 Cell Classification 12454 and dimensioned to ASTM D2467 standards for Schedule 80 PVC socket fittings.

Solid style flanges are the preferred choice when bolt hole orientation must be fixed at installation — such as equipment nozzle connections, instrumentation takeoffs, and panel-mounted assemblies — and where the rotational flexibility of a Van Stone flange is unnecessary or undesirable.

Specifications:

Fitting pressure rating reflects Schedule 80 PVC threaded connection at 73°F water service. Assembled flange joint ratings depend on gasket selection, bolt torque, and mating flange material — consult system design specifications. Derate for elevated temperatures and chemical service per manufacturer guidelines.

Industries & Applications:

The 852-007 solid style FPT flange is used wherever a permanent, bolt-hole-aligned PVC flange connection is needed on 3/4-inch threaded piping in corrosion-resistant systems:

• Chemical Processing & Water Treatment — Flanged connections on chemical dosing pumps, metering equipment, filter vessels, and instrumentation takeoffs where a fixed, non-rotating flange face is required for precise bolt alignment
• Industrial Process Piping — Equipment nozzle connections and valve isolation points on 3/4-inch chemical feed and reagent distribution lines requiring bolted PVC flange joints
• Municipal Water & Wastewater — Pump skid connections, valve isolation flanges, and instrumentation ports on treatment plant piping where PVC chemical resistance and ANSI 150 lb drilling compatibility are specified
• Semiconductor & Electronics Manufacturing — Ultra-pure water (UPW) and chemical delivery system connections where the non-reactive PVC surface and leak-free bolted joint are critical
• Agricultural & Irrigation Systems — Flanged connections to pump inlets, filter housings, and flow control equipment on pressurized 3/4-inch irrigation mains
• Laboratories & Research Facilities — Reagent and utility water line connections to equipment flanges where chemically inert, threaded PVC flanges are required
• HVAC & Cooling Systems — Chemical treatment line connections and instrument isolation points where corrosion-resistant flanged joints extend system service life
