About the Airtac BB Double Male Thread Straight Connector BB0101-S
The BB0101-S is a straight male connector with a PT 1/8 taper thread on both ends of one solid SUS304 stainless body. It is the smallest rung of AirTAC's BB ladder and the simplest way to join two fixed pipes of the same port size without any adapter in between. Sealing comes from the PT taper itself, so the thread flanks do the work, not a separate seal.
Unlike a push-in resin fitting, this family is rated for 3.0 MPa proof pressure, 0-1.0 MPa working pressure, -750 mmHg vacuum and a continuous 0 to 150 C, with the body machined from SUS304 rather than plated brass. That combination is why a fitting like this turns up close to ovens, dryers and hot compressed-air take-offs where a one-touch resin body would soften. It is also copper-free, which matters in plating shops and electronics lines where dissolved copper contaminates the process.

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 BB0101-S Is Used
Plating line air agitation
Copper-free SUS304 plumbing keeps dissolved copper out of electrolytic and electroless baths while the 3.0 MPa proof pressure absorbs pump surge on agitation spargers.
Food plant wash-down zones
A solid stainless body with no plating to flake survives daily caustic hose-down around packaging and filling machines, and the 150 C rating suits hot-CIP rinse lines.
Heated die and mould hot-air circuits
Blow-off and dryer nozzles near injection moulds run well above the 70 C ceiling of resin one-touch fittings; this 1/8 joint holds its rating to 150 C.
Is the Airtac BB Double Male Thread Straight Connector BB0101-S the Right Part?
BB0101-S sits at the bottom of the range, so there is no smaller BB part. Step up one rung to BB0102 for a 1/8 to 1/4 reducing joint, or to BB0103 for 3/8. If both ports are female sockets on your manifold rather than male threads, the same-size BU0101 double female connector is the honest alternative and uses one fewer mating thread.
Because the seal is a PT taper, plan for tape or sealant on every joint and do not over-tighten the small 1/8 thread; the fitting carries 3.0 MPa proof, but an over-stressed 1/8 port in a thin casting will not.
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 BB0101-S FAQ
It is a SUS304 stainless male connector with PT 1/8 male taper threads on both ends. Working pressure is 0-1.0 MPa (0-10 kgf/cm2), vacuum rating is -750 mmHg (10 Torr), proof pressure is 3.0 MPa and the temperature range is 0 to 150 C. The pressure and temperature figures are identical to the nickel-plated BB0101; only the material changes.
Yes. Every thread in this family is PT taper, so the joint seals on the thread flanks. Apply PTFE tape or a suitable pipe sealant to the male thread before assembly and tighten firmly but not excessively - a 1/8 PT joint needs far less torque than larger sizes. Confirm the temperature rating of the sealant as well as the tube, since on a 150 C line the sealant or tubing is usually the limiting factor, not the stainless body.
