Gripper Fittings

Chemically inert flangeless fitting with permanently attached PTFE ferrule ideal for repeat connect/disconnect

Pressure rated up to 1000psi (69 bar)

For 1/16” or 1/8” OD semi-rigid tubing

For 1/4”-28 UNF or M6 flat-bottom ports

The Dibafit™ Gripper fitting system uses a one-piece ferrule which fits permanently onto the outside of semi-rigid tubing. Ferrules have an inner PTFE sealing face ensuring that only PTFE is in the fluid path. The outer casing is stainless steel or PEEK™. The fitting nut can spin freely, eliminating tubing twist and allowing easy repeat connect/disconnect. The system is pressure rated up to 1000psi (69 bar).


A range of different colored polypropylene nuts are available to

connect 1/16” or 1/8” OD tubing into ¼”-28 UNF flat-bottom

ports. Mixed color packs include all 10 colors for easy line

identification. PEEK™ fitting nuts for use in higher temperatures

are available in standard or compact head styles and with ¼”-28

UNF or M6 threads. An ETFE blanking plug with a PTFE sealing

face is available to seal unused ports. These blanking plugs can

be used in any flat-bottom 1/4”-28 UNF port.
