*Units ≤50SCCM F.S. are shipped with M5 (10-32) Male Buna-N O-ring face seal to 1/8” Female NPT fittings.

These adaptor fittings were selected for customer convenience in process connection. It should be noted that

the 1/8” Female NPT introduces additional dead volume. To minimize dead volume, please see Accessories for

the M5 Male to 1/8”OD compression fitting.

1. Compatible with Beswick®, Swagelok® tube, Parker®, face seal, push connect and compression adapter

fittings.

2. Venting to atmosphere. Lower Pressure Drops Available, please contact Application Assistance.
