Spears 856P-060 – Frequently Asked Questions
1) Does the 856P flange come with the ring, or do I order that separately?
The ring is included. Each Spears 856P Van Stone flange spigot ships with a matched PVC ring, so you get the complete two-piece flanged assembly. What you still have to source for the joint is the gasket and the bolt set, which are not part of the fitting.
2) What is the difference between a Van Stone flange and a one-piece socket flange?
A Van Stone flange like the Spears 856P is two pieces: a stub or hub with a flared face, plus a loose backing ring that rotates freely on it. That rotation lets you spin the ring to line the bolt holes up with the mating flange after the pipe is already solvent welded, which is the whole point on long runs and on tanks or valves where you cannot twist the pipe. A one-piece flange has the bolt holes fixed relative to the socket, so the alignment has to be right when you glue it. If your bolt pattern is fixed downstream, the Van Stone saves you the rework.
3) Can I use this PVC flange on a chemical feed line?
The 856P is molded PVC, which handles a wide range of acids, bases and salt solutions, and Spears lists chemical processing and industrial fluid conveyance among its applications. Check your specific chemical and temperature against a PVC compatibility chart first, since PVC is not suitable for solvents like ketones or aromatic hydrocarbons and loses pressure capability as service temperature climbs.
4) Is a Van Stone flange the right choice for connecting PVC pipe to a pump or valve?
It is the usual pick there. Pump and valve flanges are fixed, so you cannot rotate them to find your bolt holes. The loose ring on the 856P rotates independently of the glued spigot, letting you index the holes after the pipe is set. Facility and MRO crews also like it for serviceability: the joint breaks apart at the bolts when the pump has to come out, instead of requiring a cut.
5) Which part number do I order for an 8 inch PVC Van Stone flange spigot from Spears?
Order 856P-080 for the 8 inch. The 6 inch equivalent is 856P-060. Both are the same Class 150 PVC Van Stone spigot flange with the PVC ring included, differing only in trade size.
