Description
Schedule 80 CPVC Van Stone Flange w/ Plastic Ring (SPG x Multi Bolt)
Schedule 80 CPVC Van Stone Flange w/ Plastic Ring (SPG x Multi Bolt) provides a detachable flanged transition for compatible Schedule 80 CPVC piping where a spigot connection is required on the pipe side and a multi-bolt flange connection is required at the mating component. The Van Stone configuration incorporates a rotating plastic ring that provides flexibility when aligning the flange bolt holes during assembly.
The Spigot x Multi Bolt configuration combines a CPVC spigot connection with a gasketed, bolted flange arrangement for connecting compatible valves, equipment, fittings, or other flanged components. Selection should account for nominal size, receiving socket compatibility, plastic-ring configuration, mating flange dimensions, bolt pattern, gasket requirements, system conditions, and available installation clearance.

Van Stone Flange Configuration
The Van Stone configuration uses a rotating flange ring around the CPVC fitting hub, allowing the bolt-hole orientation to be adjusted independently of the spigot connection. This provides additional installation flexibility when matching the flange to a compatible valve, fitting, equipment connection, or adjoining flanged component.
The rotating arrangement is especially useful after the pipe-side connection has been positioned because final flange alignment can be completed without turning the connected CPVC piping. The ring can be oriented toward the mating bolt pattern before the gasket and flange fasteners are installed.
Plastic Flange Ring Design
The plastic flange ring provides the rotating component of the Van Stone assembly while maintaining the specified nonmetallic ring configuration. Its independent movement allows the bolt-hole positions to be adjusted after the CPVC fitting body and adjoining piping have been placed in their intended orientation.
The ring and mating flange should be inspected before assembly to verify proper alignment and sufficient working clearance around the connection. Piping and equipment should be positioned independently so the flange fasteners are not relied upon to correct significant system misalignment.
Spigot Connection Design
The spigot connection provides a male-style CPVC end designed to fit into an appropriately sized compatible receiving socket. This arrangement differs from a socket-end flange because the flange fitting supplies the spigot rather than receiving the adjoining pipe within its own socket.
The spigot and receiving socket should be checked for nominal-size and material compatibility before permanent joining begins. Proper preparation and CPVC-compatible joining materials help establish the pipe-side connection while leaving the rotating flange ring available for final alignment.
Multi-Bolt Flange Connection
The multi-bolt flange connection creates a detachable mechanical joint with a compatible mating flange. A suitable gasket is positioned between the flange faces, while the required fasteners secure the assembly and allow the connection to be separated later when maintenance or component replacement is required.
The mating flange dimensions and bolt-hole pattern should be checked before assembly so the two flange faces align without being forced together. Adequate working space should also be maintained for gasket placement, fastener installation, progressive tightening, inspection, and future disassembly.
Installation & Selection Considerations
- Confirm the nominal size.
- Verify the plastic ring design.
- Check the receiving socket size.
- Match the mating flange bolt pattern.
- Confirm Schedule 80 CPVC compatibility.
Our CPVC fitting specialists can help review your nominal size, Schedule 80 requirements, spigot connection, receiving socket, plastic Van Stone ring, mating flange dimensions, multi-bolt pattern, gasket requirements, and available installation clearance before you order.
Frequently Asked Questions
What is this Schedule 80 CPVC Van Stone Flange used for?
It provides a detachable transition between compatible Schedule 80 CPVC piping and a compatible mating flanged component.
What does SPG x Multi Bolt mean?
The pipe side provides a spigot connection, while the opposite side uses a multi-bolt flange connection.
What is a Van Stone flange?
A Van Stone flange uses a rotating flange ring that allows bolt-hole orientation to be adjusted independently of the connected piping.
What material is the flange ring?
This configuration is specified with a plastic flange ring that rotates around the fitting hub for flange alignment.
How does the spigot connection work?
The spigot end fits into an appropriately sized compatible receiving socket for the required CPVC joining procedure.
Why is the rotating ring useful?
The rotating ring simplifies bolt-hole alignment with the mating flange without requiring the connected CPVC piping to be turned.
Is a gasket used at the flange connection?
A compatible flange gasket is typically positioned between the mating flange faces as part of the completed bolted joint.
What should I confirm before ordering?
Confirm the nominal size, Schedule 80 CPVC compatibility, spigot connection, plastic ring configuration, mating bolt pattern, gasket requirements, and installation clearance.
Important Ordering & Installation Notes
- Inspect the spigot before use.
- Clean both mating flange faces.
- Center the gasket before bolting.
- Prepare the CPVC joint correctly.
- Tighten flange fasteners evenly in sequence.
