Bijur Delimon B1371 Compression Bushing
The Bijur Delimon B1371 is a compression bushing for 5/32 in OD lubrication tubing with a 5/16-24 UNF male thread. The official listing name is “Bushing Comp 5/32 TBG”. It is a mechanical connection fitting, not a metering device, and it sets no flow rate.
This bushing joins 5/32 in OD tubing to a 5/16-24 UNF female port at junctions in single-line resistance lubrication systems. It works as part of a compression stack and carries the thread into the port. The B1371 has no metering orifice and performs no flow control function.
Official Specifications
- Tubing: 5/32 in OD, about 4 mm, metal or nylon
- Thread: 5/16-24 UNF male
- Official listing: Bushing Comp 5/32 TBG
- Companion parts: B1061 compression sleeve and B1095 compression nut
- Material: not published
The public listings do not state the body material for the B1371. The material is not published, and any material claim would be unverified. Request material certification with the quotation if the application requires a documented material.
The Compression Stack: B1371, B1061, B1095
The B1371 bushing, B1061 compression sleeve, and B1095 compression nut work as one assembly. The sleeve grips the tube, the nut loads the sleeve, and the bushing carries the thread into the port. All three parts must be present for a reliable mechanical connection.
When building a junction, order all three parts together. A missing sleeve or nut leaves the stack incomplete and the tube unsecured. The bushing alone does not complete the connection.
What It Does Not Do
The B1371 has no metering orifice and sets no flow rate. It is a mechanical connection fitting only. Metering happens in meter units elsewhere on the line.
If a point needs metered flow, order a meter unit, not a bushing. The B1371 cannot control or regulate lubricant delivery. It only provides a threaded connection for the tubing.
Where It Fits in an SLR System
The B1371 fits at junctions, headers, meter unit ports, and adapter positions in single-line resistance lubrication systems. The 5/16-24 UNF thread is the standard Bijur port thread for this tube size family. The bushing connects 5/32 in OD tubing into these ports.
For related adapter bodies, see the Bijur elbow adapter body family on this site. For broader context on how tubing and fittings work in centralized lubrication, see tubing and fittings in centralized lubrication systems.
Ordering Practice
Confirm the tubing OD, port thread, and the companion sleeve and nut part numbers at quotation. The B1371 requires the B1061 sleeve and B1095 nut to function as a complete compression stack. Verify all three part numbers before ordering.
Since the material is not published, request material certification with the quotation. For nylon tubing applications where a different retention style is preferred, see push-in fittings for nylon tubing as an alternative retention style.

Frequently Asked Questions
What is the Bijur Delimon B1371?
The B1371 is a compression bushing for 5/32 in OD lubrication tubing. It has a 5/16-24 UNF male thread and is not a metering device.
What tubing does the B1371 take?
The B1371 takes 5/32 in OD tubing, about 4 mm. Both metal and nylon tubing are used in this size family.
What thread does the B1371 have?
The B1371 has a 5/16-24 UNF male thread. This is the standard Bijur port thread for this tube size.
What material is the B1371 made of?
The material is not published in the official listings. Request material certification with the quotation if needed.
What is the B1061 compression sleeve for?
The B1061 sleeve grips the 5/32 in OD tube. It works with the B1371 bushing and B1095 nut.
What is the B1095 compression nut for?
The B1095 nut loads the B1061 sleeve onto the tube. It threads over the bushing to complete the compression stack.
Does the B1371 meter flow?
No, the B1371 has no metering orifice. It only provides a mechanical connection for the tubing.
Where is the B1371 used?
The B1371 is used at junctions, headers, meter unit ports, and adapters. It fits single-line resistance lubrication systems.
Can the B1371 take nylon tubing?
Yes, the B1371 takes 5/32 in OD nylon tubing. That size is about 4 mm in outside diameter.
