Both the Single and Dual Chamber TMCO fittings are equipped with the SureShot® Orifice Plate Seal Ring which is constructed of a Hydrogenated Nitrile Butadiene Rubber (HNBR) ……. bonded to a stainless steel ring.
The metal to metal seating of the orifice plate in the carrier design assures that there is no plate movement toward the downstream fitting tap when operating at higher differentials
The seal ring snaps in after orifice plate is installed into carrier
This creates a seal on the upstream side of the orifice plate and on the upstream side of the fitting seat
