RheFlex® M4x0.7 plugs are designed to seal off unused receiving ports in MX Series II high pressure valves

Upchurch Scientific® plugs close off unused ports in valves and multi-port connectors. Color-coded 10-32 threaded plugs are perfect for identifying stored columns that have different packing materials or when different mobile phases have been used. Cap off tubing with a PEEK™ or ETFE cap and the appropriate fitting.

This PEEK fitting has a one-piece design that eliminates the need for separate pieces to reliably close off the port
