Spears PVC One-Piece FPT Flange, CL150 150PSI
The Spears PVC One-Piece FPT Flange, CL150 150PSI, is a one-piece PVC flange fitting engineered for female-threaded (FPT) connections in pressurized PVC piping systems. Rated Class 150 (CL150) with a 150 PSI pressure rating, this one-piece PVC flange delivers a strong, corrosion-resistant connection point for PVC pipe runs, pumps, valves, and other piping equipment. Molded as a single, one-piece body rather than an assembled unit, it reduces potential leak points while simplifying installation. Packaged 10 each per carton, it is built to provide dependable, leak-resistant performance in demanding commercial, industrial, and residential plumbing applications where a durable, code-appropriate PVC connection is required.
Key Features
- Durable Construction: Manufactured from PVC for excellent corrosion and chemical resistance throughout the piping system, outperforming many metal alternatives in wet or corrosive environments.
- One-Piece Design: Molded as a single, one-piece flange body for a strong, leak-resistant connection without additional assembly, gaskets between components, or seams to fail.
- FPT Connection: Female threaded (FPT) connection allows straightforward, secure joining to male-threaded PVC pipe and fittings without solvent welding at the flange joint.
- Pressure Rating: Rated Class 150 (CL150) with a 150 PSI pressure rating for reliable, consistent performance in pressurized piping systems.
- Bulk Packaging: Packaged 10 each per carton for convenient stocking, distribution, and jobsite installation on larger plumbing projects.
- Corrosion Resistance: PVC construction resists rust, corrosion, and chemical degradation better than many metal flange alternatives, extending service life.
- Lightweight Handling: PVC construction keeps the flange lightweight relative to metal equivalents, easing handling and installation on the jobsite.

Spears 852-030 – Frequently Asked Questions
1) What sizes does the Spears 852 PVC one-piece FPT flange come in?
Two sizes: 3 inch (part 852-030) and 4 inch (part 852-040). Both are one-piece PVC flanges with a female threaded socket, so you thread them onto male-threaded pipe or a male adapter of the matching nominal size.
2) Can I use a Spears 852 PVC flange on a solvent-weld PVC pipe run?
Not directly. The 852 is an FPT (female threaded) flange, so it needs a male thread going into it. On a solvent-weld run you would solvent weld a male adapter to the pipe and thread that into the flange, or use a socket-type flange instead. The threaded hub is what lets you break the joint later without cutting pipe.
3) Will a Spears 852 PVC flange bolt up to a metal or cast iron flange on a pump?
It is a Class 150 pattern flange, which is the common bolt circle used for pump and valve connections in that class, so it mates face to face with another CL150 flange of the same nominal size. Use a full-face gasket and flat washers, and tighten in a cross pattern to a low, even torque. Over-torquing is the usual way a PVC flange gets cracked against a rigid metal face.
4) What pressure is the Spears 852 flange rated for?
Class 150 with a 150 PSI rating. That is the flange itself; on any flanged joint the bolt-up and gasket also have to be right, and PVC pressure ratings fall off as fluid temperature rises, so size the system to the lowest-rated component in the run.
5) Do I need to add a gasket and bolts when I order the 852 flange?
Yes. The flange is the fitting only. A flanged joint also needs a full-face gasket between the mating faces plus bolts, nuts and washers sized to the Class 150 bolt pattern for your 3 inch or 4 inch connection. Plan on those as separate line items.
6) Is the Spears 852 flange sold individually or by the box?
Packaged 10 each per carton. That works for a contractor or distributor stocking a repeated size, less so if you only need a single flange for one pump connection.
7) Does the one-piece flange body mean fewer leak paths than a two-part flange?
Yes. The 852 is molded as a single body rather than a hub and a loose ring assembled together, so there is no seam or secondary gasket inside the fitting itself. The only sealing points left are the threaded joint into the hub and the gasket between the two flange faces.
