Bijur Elbow Adapter Bodies for Nylon Tubing
This family covers 90 degree elbow adapter bodies that adapt a machine port to a nylon tube connection. The tube side uses a compression-style interface with tube nut and insert. These aftermarket cross-reference bodies serve multi-line and progressive lubrication systems running 5/32 in (4 mm) and 1/4 in nylon tubing.
Bijur part numbers are shown for cross-reference identification only.

Adapter Body or Elbow Connector
An elbow adapter body is a 90 degree fitting that adapts a machine port to a tube connection. The tube side uses a compression-style interface with tube nut and insert. An elbow connector in Bijur taxonomy is a thread-to-thread 90 degree fitting without the tube port. Bijur lists 90 degree elbow adapter bodies under fittings.
This distinction matters when ordering because a connector will not accept a tube nut and insert. An adapter body includes the tube-side interface needed for nylon tubing retention.
Inch-Series Bodies
B6536: 1/4 in OD tubing, 1/8 NPT male x 5/16-24 female tube connection.
B3431: 3/32 in OD tubing, 1/8 NPT male x 5/16-24 female.
19285: 5/32 in (4 mm) tubing, 1/4-28 male x 5/16-24 female.
5/16-24 is the standard tube-side interface for 5/32 in tubing. The machine-side thread standard must be confirmed separately for each port.
Metric-Series Bodies
20350: 4 mm (5/32 in) tubing, M6 x 0.75 male x M8 x 1 female.
19454: 4 mm (5/32 in) tubing, M6 x 1 male x M8 x 1 female. Distributor listings put this form at up to 150 psi and -40 to +93 °C.
26810 and 25302 belong to the metric and mixed-thread adapter families. Public listings do not expose complete reliable thread pairs, so confirm exact pairs from the quotation form.
For the same M6 x 1 to M8 x 1 form, see the LUBE 106076 elbow adapter page.
The A3080 Thread Question
A3080 covers 5/32 in (4 mm) tubing. Bijur service-parts material lists R1/8 BSPT male x M8 x 1 female. A distributor table renders the style as 1/8 NPT. Catalog editions and listings differ, so verify the thread standard against the drawing before ordering.
NPT and BSPT are different standards and are not interchangeable. Selecting the wrong machine-side thread can damage the port or prevent sealing.
Choosing the Right Body
Tubing OD alone is not enough. The insert and ferrule, the tube-side interface (5/16-24 or M8 x 1), and the machine-side thread standard (NPT, BSPT, or metric) must all match.
For context on how these bodies fit into tubing runs, see centralized lubrication system tubing runs.
If you need a different retention style, see push-in fittings for nylon tubing.

Frequently Asked Questions
What is the difference between an adapter body and an elbow connector?
An adapter body has a tube-side interface for a tube nut and insert. An elbow connector is thread-to-thread only.
Which body fits 1/4 in OD nylon tubing?
B6536 fits 1/4 in OD tubing with 1/8 NPT male threads. The tube side is 5/16-24 female.
Which body fits 4 mm tubing with metric threads?
20350 uses M6 x 0.75 male with M8 x 1 female. 19454 uses M6 x 1 male with M8 x 1 female, and both fit 4 mm tubing.
What does 5/16-24 mean on these bodies?
5/16-24 is the standard tube-side interface for 5/32 in tubing. It accepts the tube nut and insert, while the machine side uses a separate standard.
Why do A3080 listings show different threads?
Bijur service-parts material lists R1/8 BSPT male x M8 x 1 female, while a distributor table renders it 1/8 NPT. Verify the drawing before ordering.
Are NPT and BSPT interchangeable?
No, NPT and BSPT are different thread standards and are not interchangeable. Using the wrong standard can damage the port.
Is a tube insert needed with these bodies?
Yes, the tube side uses a compression-style interface with a required tube nut and insert. The insert supports the nylon tubing wall.
Is the LUBE 106076 the same form as 19454?
Yes, the LUBE 106076 matches the M6 x 1 to M8 x 1 form. It is a separate brand equivalent page linked in the metric section.
What are 26810 and 25302?
They belong to the metric and mixed-thread adapter families without complete public thread pairs. Confirm exact pairs from the quotation form.
