Omnifit 1/4''-28 UNF to small variable bore adaptors

for 0.5 to 4mm OD tubing

• Variable bore adaptors

• Low dead volume

• 50 psi pressure rating

• 1.5mm bore size

• Chemically inert all-PTFE body

• Polypropylene or Tefzel® caps

Connectors for 1/4"-28 UNF to Omnifit 'cap-type' variable bore connectors. Valved versions are available with a Tefzel® rotor.

1/4"-28 UNF connection
Each adaptor has a male 1/4"-28 UNF thread at one end. This will fit any female 1/4"-28 UNF threaded port.

Omnifit 'cap-type' connection
Each adaptor has an Omnifit 'cap-type' connection at one end, which accepts any hardwall tubing between 0.5 and 4mm outer diameter.

Omnifit Cap Adaptors
Replace the Omnifit cap on any Omnifit connector or valve

• Push-on connection for softwall tubing

• Adaptors with Luer fittings

• Adaptors with Tefzel® or stainless steel pipe

• Autoclavable

Cap Adaptors replace the coloured cap on any of Omnifit's small variable bore connectors and valves to give either quick push-on connections for softwall tubing or Luer connections.
Cap to Luer adaptors
Adaptors to give either male or female Luer connections are available.
Cap to pipe adaptors
Adaptors to three pipe sizes are available in Tefzel® or stainless steel to take softwall tubing of the corresponding inner diameter:
~ 1/4" OD
~ 1/8" OD
~ 1/16" OD

Barbed adaptors Barb to thread adaptors

• PEEK & trade material

• Excellent chemical resistance

• Extra sharp machined barbs for resilient connections

Omnifit barbed adaptors are designed for use with soft wall tubing.
They are manufactured by turning on C.N.C. machines rather than moulded and this ensure an extra sharp barb to retain soft wall tubing.

Threaded ends are available in male or female thread types.

 Thread to thread couplings 

• Straight-through female couplings

• Excellent chemical resistance

• PEEK, Tefzel or Polypropylene

• Convert different thread sizes

 Omnifit threaded couplings are a useful range of 'problem solving' parts that enable you to convert thread sizes quickly and easily.

Omnifit couplings are available that accept a 1/4"-28 UNF male fitting at one end and convert this to a range of male and female thread types:

~ 1/4"-28 UNF female
~ 10-32 female
~ 1/8" NPT male
~ 1/8" BSPT male
