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-torquing nuts


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™.

Thisensures the system stays sealed up to 1000psi (69 bar)

pressure, even in shallow PTFE ports. The fitting nut can spin

freely, eliminating tubing twist. A recess in the fitting

houses the ferrule, allowing maximum thread engagement

with the port.

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. Technical specifications
