About the Airtac BB Double Male Thread Straight Connector BB0202
The BB0202 is a straight male connector: a single nickel-plated body with a male 1/4in PT thread on each end, used to join two fixed 1/4in ports or extend a run of 1/4in pipework in a straight line. There is no tube side at all - both ends are threads - so the joint is made up permanently with the pipework rather than plugged with hose.
This family sits apart from one-touch resin fittings: proof pressure is 3.0 MPa, twice the one-touch figure, working pressure runs 0-1.0 MPa, vacuum is rated to -750 mmHg (10 Torr), and the temperature window is 0 to +150 C. That combination is why BB0202 turns up close to ovens, dryers and moulding tools where a push-in body would soften or blow off. One caution when fitting: AirTAC publishes no tightening torque for this part, so assemble with a suitable PT thread sealant and tighten to a sound, leak-free joint by feel.

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 BB0202 Is Used
Compressor aftercooler take-off
Joining 1/4in PT pipe runs downstream of an aftercooler, where the air is still well above 70 C and a resin push-in fitting would distort or loosen over time.
Autoclave and steriliser services
Extending 1/4in pneumatic or instrument air lines on steam-adjacent sterilising plant, using the 0 to +150 C window for the hot zone outside the chamber jacket.
Injection mould tool air blast
A fixed 1/4in-to-1/4in air-blast connection on a moulding tool, where vibration and mould heat punish push-in fittings and a threaded joint clamped once stays put.
Is the Airtac BB Double Male Thread Straight Connector BB0202 the Right Part?
BB0202 is the 1/4in-to-1/4in equal-size member of a nine-part BB ladder. Step down to BB0101 or BB0102 (1/8in ends, or 1/8in to 1/4in) for compact instrument panels and small actuators; step up to BB0203 (1/4in to 3/8in) or BB0303 (3/8in to 3/8in) when the run feeds larger-bore pipework and you need more capacity, which scales with the bore. Pick the equal 0202 when both ports are already 1/4in - it keeps the flow path straight with no reduction. If one side is female, a BD0202 does not exist in this range, so check the BD ladder (0102 up to 0304) or add a separate 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 BB Double Male Thread Straight Connector BB0202 FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2); vacuum to -750 mmHg (10 Torr); proof pressure 3.0 MPa; operating temperature 0 to +150 C; body nickel-plated with a male 1/4in PT thread on both ends (ordering code 0202). No flow value is published - capacity follows the straight 1/4in bore, so for larger flows step up to BB0203 or BB0303.
The threads are PT (R-seal taper) only - there is no NPT or G variant of this part, so use a PT-compatible sealant or tape. Slide the joint onto the first port, thread both ends hand-tight, then wrench each down evenly. AirTAC publishes no torque figure for this family; tighten until the taper seats and the joint is leak-free under 1.0 MPa, rechecking after the first hot cycle.
