Fittings & Connection Systems

Diba offers a versatile range of fittings and systems for connecting different types of tubing quickly, easily and securely.

Click-N-Seal®

Diba’s patented Click-N-Seal® fittings are the only multi-use finger-tight fittings that cannot be over-tightened. The Click-N-Seal® family of connectors are available in polycarbonate, polyoxymethylene (POM) and PEEK and accommodate flares, ferrules and barbs. In addition, the PEEK Click-N-Seal® Ultra fittings are compatible with both flat bottom and HPLC cone-tip ports, with pressure rating up to 2500 psi (180 bar).

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 without damaging the port through over-tightening. The fitting can be unscrewed and reused dozens of times.

Click-N-Seal® Plus offers a compact head design made of POM. Click-N-Seal® Ultra offers a compact head design and PEEK™ construction for the highest standard of chemical inertness.

Click-N-Seal® fittings – Standard, Plus and Ultra are compatible with Diba flares, any of the ferrule types, or with inverted cones. Simply select the ferrule system that offers the pressure rating you require and then pair the appropriate ferrule with a Click-N-Seal®, Click-N-Seal® Plus or Click-N-Seal® Ultra fitting.

Microfluidics Connections

Click-N-Seal® Micro 6-40 Fitting for Microfluidic Applications

The Diba Click-N-Seal® Micro 6-40 fitting, ferrule and flare solutions quickly and easily connect 1/16″ tube into 6-40 threaded ports, making them ideal for systems that require smaller fluid connections. They ensure leak-free connections without risk of over- tightening.

•For microfluidics applications

•PEEK™ construction

•Pressure rating up to 50 psi (3 bar)

•Retains 1/16” OD tubing

The same torque-release fitting you have known and loved for ¼-28 fittings is now available in 6-40 fittings for microfluidics appilcations. As the fitting is tightened, the resistance of the cap increases until the correct torque is reached, at which point, the cap clicks.

Gripper

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

A range of different colored polypropylene fittings 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™ fittings for use in higher temperatures are available in standard or compact head styles and with ¼”-28 UNF, M6 or 10-32 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.

 

Insert Barbs

MicroBarb®

MicroBarb® provides a secure, low-carryover connection between flexible soft tubing and semi-rigid tubing. Two components ensure that both the ID and OD of the soft tubing are firmly gripped, ensuring a secure connection. The barbed component fits inside the tube ID and creates a flat surface for connection. The threaded outer connector slips over the tubing OD and secures the barb in place, creating a female threaded flat-bottom port.  PEEK™ construction gives a chemically inert and robust connection.

Barbed Adapters

Diba barbed adaptors are designed for use with soft-wall tubing. Machined from chemically resistant PEEK™ or acetal they have a superior barb with a crisp edge that retains soft wall tubing more securely than molded adaptors. A tight, leak-free connection can be ensured by matching the ID of your tubing to the barb size of the adaptor. If there is not an exact match, always choose the barb size that is just larger than your tubing ID.

Omni-Lok Fittings & Ferrules

 

The Omni-Lok™ fitting system is a group of products specifically designed for optimum performance within a threaded port that is of a shallow depth, and/or is made from PTFE.

Shallow ports mean less threads with which the fitting nut can engage. PTFE ports exhibit less strength than for instance a PEEK port. These factors may lead to thread stripping from the PTFE port, a less than optimum seal integrity in the case of a shallow port, or both.

Omni-Lok™ fittings are available for several connection types such as Omni-Lok™ Type P, Omni-Lok™ Type S, Omni-Lok™ inverted cone and Omni-Lok™ Gripper.

Omni-Lok™ Type P Ferrules

The Omni-Lok™ Type P fitting system uses a one-piece ferrule which fits permanently to the outside of the 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 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 1000 psi (69 bar) pressure.

Omni-Lok™ Type S Ferrules

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™ sealing surface surrounded by a stainless steel lock ring with only the inner portion in the fluid path. The fitting 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 500 psi (33 bar) pressure.
