Note: Vessels sold complete with End Plugs, U-Pins, Feed Plug and O-Rings. Mounting Pads and Straps not included. Membrane Interconnectors are sold separately.

Warning: PVC pressure vessels are limited to a maximum pressure of 200 psi (14 BAR) at 77°F (25°C). Higher pressure, higher temperature water or water hammer will lead to a premature failure. It is highly recommended that when these conditions exist, a pressure switch or relief valve be installed to protect the vessel. Alternately, you may consider a stainless steel or FRP vessel.
