Orifice Plates

Our innovative Orifice Plate line includes a complete selection of solid PTFE, Tuf-Steel®, or a 316L Stainless Steel Orifice Plate molded to a Rubber Fab elastomer, in standard, tabbed, and vertical Tri-Clamp® styles, that can be custom drilled with an eccentric or concentric bore. 

Mini Orifice Plates
Steam trap mini orifice plates are an alternative to standard steam trap technology.

Eccentric and Concentric drilled plates

  • Self Draining

A major safety consideration! Rubber Fab’s orifice plates can advance your systems performance, adjust flow rates, balance backflow and equalize backpressure during SIP procedures. Achievable benefits while maintaining sanitary conditions.

Tabs help to acknowledge that an orifice plate is “in line” and can be laser engraved to indicate the hole diameter, gasket size or user specified information.  This Tabbed design of sanitary orifice plate, when coupled with Rubber Fab's slotted clamp, allows the operator complete flexibility when balancing a sanitary pipeline system.
