Description
Schedule 80 PVC Van Stone Flange (Spigot)
Schedule 80 PVC Van Stone Flange (Spigot) provides a spigot-to-flanged transition for compatible Schedule 80 PVC piping arrangements. The spigot connection is designed to fit into an appropriately sized compatible receiving socket, while the Van Stone flange configuration provides a bolted interface for connection to a compatible mating flange.
The Van Stone flange design separates the flange ring from the piping-side hub so bolt-hole alignment can be adjusted independently during final assembly. Selection should account for nominal size, Schedule 80 PVC compatibility, receiving socket requirements, mating flange configuration, gasket selection, bolt alignment, service conditions, adjoining piping support, and available installation clearance.

Van Stone Flange Design
The Van Stone flange configuration separates the flange ring from the piping-side hub, allowing the bolt-hole orientation to be adjusted independently during installation. This arrangement can simplify final alignment with a compatible mating flange after the spigot-side piping connection has established the position of the hub.
Independent flange-ring positioning reduces the need to rotate connected piping simply to line up the flange fasteners. The hub establishes the piping transition while the flange portion provides the mechanical mating interface, allowing the two connection functions to be coordinated during final assembly.
Spigot Connection
The spigot connection provides an exterior joining surface designed to fit into an appropriately sized compatible receiving socket. This allows the piping side of the Van Stone flange to connect through a PVC solvent-cement joint while the opposite side provides the mechanical flange connection.
The spigot and receiving socket should be prepared using joining practices appropriate for the PVC piping system. Correct insertion, compatible joining materials, proper alignment, and careful positioning help establish the piping-side connection while maintaining the intended orientation of the flange assembly.
Flange Alignment & Assembly
The flanged interface connects to a compatible mating flange using the appropriate gasket and fastener arrangement. Proper alignment allows the mating flange faces to meet naturally and helps prevent the bolts from being used to pull misaligned piping or equipment into position during assembly.
The gasket should remain centered while the flange fasteners are installed and tightened progressively using an appropriate sequence. Even tightening helps distribute assembly forces around the joint, while independent support for adjoining piping reduces unnecessary bending and alignment loads on the completed flange connection.
Schedule 80 PVC Integration
A Schedule 80 PVC Van Stone Flange (Spigot) provides a practical transition where compatible socket-connected PVC piping must interface with a flanged valve, fitting, equipment connection, or adjoining piping component. The spigot end establishes the PVC piping connection while the Van Stone arrangement provides flexibility during final flange alignment.
Application suitability should be evaluated using the requirements of the complete piping system rather than the Schedule 80 designation alone. Receiving socket compatibility, mating flange requirements, service conditions, gasket selection, joining materials, piping support, installation environment, and applicable installation practices should all be considered during selection.
Installation & Selection Considerations
- Confirm the nominal size.
- Verify the mating flange style.
- Check Schedule 80 PVC compatibility.
- Match the spigot to the receiving socket.
- Allow clearance for flange and bolt alignment.
Our PVC fitting specialists can help review your nominal size, Schedule 80 requirements, spigot connection, receiving socket, mating flange configuration, gasket requirements, bolt alignment, service conditions, adjoining piping support, and available installation clearance before you order.
Frequently Asked Questions
What is a Schedule 80 PVC Van Stone Flange used for?
It provides a transition between compatible Schedule 80 PVC piping and a mating flanged component using a spigot piping connection.
What does spigot mean?
Spigot identifies an exterior joining surface designed to fit into an appropriately sized compatible receiving socket.
What does the spigot end connect to?
The spigot end fits into an appropriately sized compatible receiving socket for the applicable PVC solvent-cement joining procedure.
What is a Van Stone flange?
A Van Stone flange uses a separate flange ring around the piping-side hub so its bolt-hole orientation can be adjusted during installation.
Why is the Van Stone configuration useful?
It allows the flange bolt holes to be aligned with the mating flange without rotating the connected piping solely for fastener positioning.
How is the spigot connection assembled?
The spigot and compatible receiving socket are prepared and joined using the appropriate PVC solvent-cement joining procedure.
Important Ordering & Installation Notes
- Inspect the spigot before use.
- Center the gasket before bolting.
- Prepare the receiving socket correctly.
- Tighten flange fasteners evenly in sequence.
- Support adjoining piping independently of the flange.
