We offer a range of different fitting systems to suit a variety of applications. In each system, a range of different colored polypropylene nuts are available to connect 1/16” or 1/8” OD tubing into ¼”-28 UNF, M6 or 5/16”-24 UNF flat-bottom ports. PEEK™ fitting nuts for use in higher temperatures are available in standard or compact head styles and with ¼”-28 UNF or M6 threads.

A 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

The Omni-Lok™ 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 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. Note: Omni-Lok™ Type P for 3/16” OD tubing and 5/16”-24 UNF flat-bottom ports is pressure rated up to 200 psi (14 bar).

A chemically inert flangeless fitting with permanently attached PEEK™ or ETFE ferrules, ideal for repeated connect/disconnect

• Pressure rated up to 500psi (34 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
• PEEK™ ferrules can be used with rigid tubing, e.g. PEEK™

The Omni-Lok™ Type S fitting system uses a two-piece ferrule which fits permanently to the outside of the tubing. Two-part ferrules consist of an inner PEEK™ or ETFE sealing surface surrounded by a stainless steel lock ring with only the inner portion in the fluid path. The fitting nut can spin freely against the ferrule, eliminating tubing twist and subsequent loosening of the nut. A recess in the fitting houses the ferrule, allowing maximum thread engagement with the port ensuring the system stays sealed up to 500psi (34 bar) pressure even in shallow PTFE ports. Note: The Omni-Lok™ Type S for 3/16” OD tubing and 5/16”-24 UNF flat-bottom ports is pressure rated up to 200 psi (14 bar).

A removable and reusable system for quick and convenient low-pressure connections

• Pressure rated up to 250psi (17 bar)
• For 1/16”, 1/8” or 3/16” OD and metric sizes 2.0, 2.5 or 3.0mm OD semi-rigid tubing e.g. PTFE, ETFE, FEP
• For flat-bottom ¼”-28 UNF, M6 or 5/16”-24 UNF ports

Omni-Lok™ inverted cone fittings provide a simple, easy to use low-pressure connection. Only the ETFE cone is in the fluid path. Note: The Omni-Lok™ inverted cone and fitting nut for 3/16” OD tubing and 5/16”-24 UNF flat-bottom ports is pressure rated up to 30 psi (2 bar).

Flanged (flared) tubing system for economical low-pressure connections

• Pressure rated up to 250psi (17 bar)
• For 1/16”, 1/8” or 3/16” OD semi-rigid tubing, e.g. PTFE
• For flat-bottom ¼”-28 UNF ports
• Removeable and reusable

Omni-Lok™ flanged fittings require the end of hardwall tubing to be formed into a flange (flare). A flanging washer is placed between the flange and the fitting nut. When screwed into a flat-bottom, the flange is compressed against the bottom of the port to produce a seal. Only the tubing is in the fluid path.

A 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 Omnifit® 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 fitting nut can spin freely, eliminating tubing twist and allowing easy repeat connect/disconnect. The system is pressure rated up to 1000psi (69 bar).

Hand-tight fittings without the guesswork

• For Omni-Lok™ Type P & Type S ferrrules or inverted cones
• For 1/16” or 1/8” OD semi-rigid tubing
• Feel and hear when the fitting is properly installed

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.
