Stainless Union Orifice Connector for 1/4" Diameter Stainless Tubing

Stainless Steel Union Orifice Connector RB82631 connects 1/4" stainless tubing inline. Sapphire or ruby orifices are swaged in place by proprietary methods. For elevated pressure applications the flow should push the orifice into its seat in the connector for best results.

RB82631 is available with all three orifice styles. Sizes range from 0.0004" thru 0.081".
