About the Airtac BD Female-Male Straight Connector BD0102
The BD0102 is a reducing connector that marries two thread sizes in one nickel-plated part: Thread I is a 1/8in PT female port, Thread II is a 1/4in PT male stud. It exists so a line can step from a small branch port up to a 1/4in supply without stacking a straight connector on a separate reducing bush.
This family is built for conditions that stop a push-in resin fitting cold. Working pressure is 0-1.0 MPa with a -750 mmHg vacuum rating, and the proof pressure is 3.0 MPa - three times the working figure - while the temperature window runs from 0 to +150 C. The resin one-touch range tops out around 70 C, which is why these metal connectors turn up on hot compressors, ovens and moulding tools instead. Note the thread standard is PT throughout; no NPT or G variant exists.

Nickel-plated metal body. AirTAC does not publish a per-part material breakdown for this family. This family is rated to 150 °C, but the TUBE is usually the limit - confirm your tubing's temperature rating before running it hot. AirTAC publishes flow as a characteristic curve rather than a single figure, so no L/min value is listed.

Fitting & Sealing Notes
- check Cut the tube square and clean before pushing it home, or the seal will leak.
- check Push until it stops, then pull back to check the chuck has gripped.
- check To release, press the collet ring fully in and pull the tube out.
- check Threaded parts arrive with sealant on the thread; M5 sizes use a sealing gasket.
- check Match the tube OD exactly - a 6 mm fitting will not hold 1/4" tube.
Where the Airtac BD Female-Male Straight Connector BD0102 Is Used
Trailer brake and auxiliary air lines
Commercial vehicle and trailer pneumatic circuits step between 1/8in gauge take-offs and 1/4in supply runs; the 3.0 MPa proof margin covers the shock loads of compressor cut-out and emergency braking.
Autoclave and steriliser instrumentation
Laboratory autoclaves run sensor and actuator lines close to steam temperature. The 0 to +150 C window lets the BD0102 sit near the chamber where a resin fitting would soften, and the -750 mmHg rating survives the vacuum draw-down phase.
Textile stenter frame actuators
Stenter and heat-setting machines run heated air well above 100 C across their gantries. The 1/4in male stud plugs straight into the frame's tapped branches, and the nickel-plated body resists the finish-laden atmosphere.
Is the Airtac BD Female-Male Straight Connector BD0102 the Right Part?
BD0102 is the smallest combination in the BD ladder - there is no reducing pair below it. The equal-size alternatives at 1/8in are the BB0101 male connector or BU0101 double female; step up to BD0103 (1/8in female x 3/8in male) when the mating stud is a half-inch-equivalent branch. Going one step up in the male thread gains bore and flow capacity but costs a size in the female port you are threading into.
Choose a BD over a BB plus a bushing wherever the connection is made up permanently: one joint, one thread path, one potential leak point instead of three. If the 1/8in port is simply unused, a BZ01 plug is the more honest answer than an adapter.
Quick checklist
- ✓ Tube outside diameter matches exactly
- ✓ Thread size and standard match the port
- ✓ Working pressure within 0 - 1.0 MPa (0 - 10 kgf/cm2)
- ✓ Temperature within 0 to +150 °C
Airtac BD Female-Male Straight Connector BD0102 FAQ
It is a reducing connector with a PT 1/8in female thread (Thread I) and a PT 1/4in male thread (Thread II). Working pressure 0-1.0 MPa (0-10 kgf/cm2), negative pressure -750 mmHg (10 Torr), proof pressure 3.0 MPa, and a temperature range of 0 to +150 C. The body is nickel plated. No flow coefficient is published; capacity follows the orifice, so treat the 1/8in female port as the restrictive side.
AirTAC does not define which physical end carries Thread I versus Thread II, so confirm by measuring the two ends before assembly - one is the 1/8in female bore, the other the 1/4in male stud. Both are PT (tapered pipe) threads, so use PTFE sealant tape or pipe dope on the male 1/4in thread; do not substitute NPT hardware, which has a different thread form and will not seal reliably.
