About the Airtac BB Double Male Thread Straight Connector BB0102
The BB0102 is AirTAC's male-thread connector in the BB family: male PT thread on both ends, stepping from 1/8in down to 1/4in. It is the piece you reach for when a 1/4in port on a valve plate or machine manifold has to feed a 1/8in branch line, made up permanently rather than unplugged every shift. The body is nickel plated and carries PT (parallel taper) threads on AirTAC's 01/02 code ladder, where 01 means 1/8in and 02 means 1/4in.
What sets this family apart from the resin one-touch range is the pressure and temperature headroom: 0-1.0 MPa working pressure, -750 mmHg vacuum, a 3.0 MPa proof rating - three times the working figure - and a 0 to +150 C operating window. That is why the BB0102 shows up around ovens, dryers and moulding tools where a push-in plastic fitting would soften long before the process ends. Keep in mind that the connected tube's own temperature rating usually becomes the limit before the fitting does.

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 BB Double Male Thread Straight Connector BB0102 Is Used
Injection mould hot-runner purge air
Steps a 1/4in mold-base air port down to 1/8in purge lines around a hot runner, where mould-deck temperatures would creep past the 70 C ceiling of resin one-touch fittings.
Textile stenter dryer frame circuits
Feeds 1/8in cylinder and flap-control lines off the 1/4in supply rail of a stenter or drying oven, standing up to the 150 C ambient that baked fabric frames generate.
Bakery oven damper actuation
A permanent 1/8in to 1/4in adaptor on rotary damper cylinders beside a commercial baking oven, assembled once and sealed so no plastic body ever sits in the heat path.
Is the Airtac BB Double Male Thread Straight Connector BB0102 the Right Part?
Step down and step up on the 1/4in side of this code: BB0101 pairs 1/8in with 1/8in when the whole run is small-bore, while BB0103 pairs 1/8in with 3/8in if the supply port is larger. If both ends should be 1/4in, that is BB0202. All three exist in the catalogue - nothing between or outside these steps does.
If one end of your interface is a female port instead, compare BD0102, which keeps the same 1/8in to 1/4in step but puts a female thread on Thread I. It often beats a BB0102 plus a separate male-to-male adapter by removing a joint, and every joint you remove is one more place sealant can weep at 150 C.
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 BB Double Male Thread Straight Connector BB0102 FAQ
The BB0102 is a male-to-male pipe connector with 1/8in PT on one end and 1/4in PT on the other. Working pressure is 0-1.0 MPa (0-10 kgf/cm2), negative pressure is -750 mmHg (10 Torr), proof pressure is 3.0 MPa and the temperature range is 0 to +150 C. The body is nickel plated. Note that PT threads are the standard here - no NPT or G variants exist in this family.
Because PT is a parallel taper thread, wrap the male threads with PTFE sealant tape (or apply liquid thread sealant) before threading into the port, and tighten with a spanner on the hex. AirTAC publishes no tightening torque for this family, so tighten to a sound seal rather than a stated figure. Do not fit this part to an NPT or G port - the thread forms are not interchangeable and a cross-standard joint is the usual cause of leaks at temperature.
