Snyder Industries 6 Inch Double Flanged Fitting (CPVC) Bolted with EPDM Gasket and S.S. Encapsulated Bolts

What to check before you buy

1. The size. 6 inch. The valve, flange adapter and pipe downstream have to match, so settle the size first and buy the rest to suit.
2. The liquid. CPVC body, EPDM gasket, stainless bolts under the encapsulation. Check the liquid against the body and the gasket in our chemical compatibility guide; if it calls for a Viton gasket instead, Snyder makes that version and we can swap it on the order.
3. The wall. The flange needs a flat, continuous area of wall at least as wide as itself, with the bolt holes clear of any rib or corner. Snyder's drawing, linked on this page under Technical Drawing, shows the flange, the hole and the bolt pattern.
4. Access. Somebody has to reach the inside flange to install it. On a closed tank that means a manway big enough to work through; tell us the tank and we confirm it.

Installing it

Dry-fit the two flanges with the gasket between before you drill a single bolt hole, and turn the assembly so the outside face lines up with the pipe run. Pull the bolts up evenly in a cross pattern, a little at a time, so the gasket is squeezed flat rather than pinched on one side. Keep a slipping wrench off the encapsulation; the plastic jacket is what keeps the liquid off the metal. Support the valve and the first length of pipe on their own so the wall carries liquid, not hardware. Fill with water the first time and look at the joint before anything else goes in.

Shipping

A 5 lb fitting in a 10 by 10 by 10 inch carton, by UPS from Snyder's Lincoln, Nebraska plant when ordered loose. Fittings installed on a tank at the factory ship with the tank from that tank's plant. The listed price is before freight; the freight cost estimator gives the cost to your ZIP. Ordering it with a tank? Put both on one order.
