About the Airtac BB Double Male Thread Straight Connector BB0102-S
The BB0102-S is a straight male connector in solid SUS304 stainless steel: PT 1/8in male thread on one end, PT 1/4in male thread on the other, used to join two tapped ports of different sizes in a straight run. There is no tube entry on this part at all - it is a pure thread-to-thread adapter, which is exactly why it survives conditions that destroy push-in resin fittings. AirTAC does not publish which physical end corresponds to Thread I, so it can be installed either way round.
The family rating is what earns it a place near heat: 3.0 MPa proof pressure (double the one-touch resin figure), 0-1.0 MPa working pressure, 10 Torr vacuum capability, and a continuous temperature window of 0 to 150 C. In the -S variant the whole body is SUS304 rather than a plated part, so the corrosion resistance is in the material itself, not a coating that can be scratched off at the wrench flats.

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. Stainless (-S): SUS304 body throughout, for copper-free and corrosive environments. Pressure and temperature ratings are unchanged from the nickel-plated version. 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-S Is Used
Shrink-tunnel and heat-sealer air circuits
Benchtop shrink tunnels and impulse heat sealers run compressed-air actuation within centimetres of heating elements. At 150 C continuous the BB0102-S brass-free stainless body shrugs off radiated heat that softens a resin one-touch within weeks.
Electronics and plating-line pneumatic takeoffs
On PCB wash lines and electroplating jigs, dissolved copper can catalyse contamination in process baths. Solid SUS304 construction keeps copper out of the wet zone while the 1/4in end ties into the main manifold drop.
Permanent gauge and branch tees on moulding tools
Injection mould and die toolmakers plumb air-blow and ejector-assist lines that are made up once and never serviced in place. A hard stainless threaded adapter at a 1/8in-to-1/4in transition survives tool cleaning and thermal cycling better than any clip-in joint.
Is the Airtac BB Double Male Thread Straight Connector BB0102-S the Right Part?
Step down to BB0101 if both ports are 1/8in, or up to BB0103 if the larger port is 3/8in - both exist in the BB ladder. Stepping the big end up increases the thread engagement and the spanner size but changes nothing in the pressure or temperature rating. If one side of your junction is a female port rather than male, BD0102 (female 1/8in, male 1/4in) does the same job without a separate adapter. BB0102-S never connects to tubing - only the BKC locknut fittings in this catalogue take a tube.
Seal the threads with PTFE tape or pipe sealant applied to the male thread; AirTAC publishes no tightening torque for these parts, so tighten to a sound seal and avoid over-stressing the smaller 1/8in member.
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-S FAQ
It is a straight male pipe connector with PT 1/8in and PT 1/4in male threads, machined in SUS304 stainless steel. Working pressure 0-1.0 MPa (0-10 kgf/cm2), negative pressure down to -750 mmHg (10 Torr), proof pressure 3.0 MPa, and an operating temperature range of 0 to 150 C. Thread standard is PT throughout - no NPT or G variant exists in this series. No flow coefficient is published for the family; capacity follows the port bore.
Measure it - AirTAC's ordering code lists Thread I then Thread II, but the catalogue does not clearly state which physical end is which, so treat the part as reversible and check both ends with a thread gauge. The fitting practice is standard taper-thread work: sealant or PTFE tape on the male threads, wrench on the hex, no published torque figure, and never back the joint off once sealed to re-align it.
