Sapphire Ball Seat for Check Valve

Sapphire Ball Seats are used as check valves in pumps. Using a Grade 5 sapphire or ruby ball in conjunction with the seat will provide a seal due to matching points of contact. Our stock sapphire seat matches with a 1/8″ diameter ball (Model No. B3.18S, B3.18R). Custom design is welcome.

Typical Applications: Liquid Chromatography, Flow Control
