Rubber Fab Steam Trap Mini Orifice Plates

Excellent for hot water and low pressure steam services

Our innovative Orifice Plate line includes a complete selection of solid 316L Stainless Steel, in standard or tabbed tri-clamp that can be custom drilled with an eccentric or concentric bore. Vertical styles, which are funnel shaped for optimal vertical drainage, are also available.

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