p Ferrule System

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

Pressure rated up to 1000psi (69 bar)

For 1/16”, 1/8” or 3/16” OD semi-rigid tubing e.g. PTFE, ETFE, FEP

For flat-bottom 1/4”-28 UNF, M6 or 5/16”-24 UNF ports

Use with Omni-Lok™ compact head or Click-N-Seal™ self-

The Dibafit Type P 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. A recess in the fitting houses the ferrule, allowing maximum thread engagement with the port. This ensures the system stays sealed up to 1000psi (69 bar) pressure, even in shallow PTFE ports.

Omni-Lok™ nuts

Omni-Lok™ compact head fitting nuts, in glass-filled

polypropylene, are available in a range of different colors for

easy line identification. Other options are a longer length nut

for applications where accessibility is an issue (1/8” OD tubing

only) and standard head nuts in PEEK™ for higher temperatures.

Click-N-Seal™ nuts

Click-N-Seal™ offers a unique system for hand-tight fittings. As

the fitting is tightened, the resistance of the cap increases until

the correct torque is reached; at which point, the cap clicks.

The user is able to hand-tighten the fittings without tools or

guesswork and be confident that the fitting is properly seated,

creating a secure seal. The fitting can be unscrewed and reused.
