About the Airtac BB Double Male Thread Straight Connector BB0202-S
The BB0202-S is a straight male connector in solid SUS304 stainless steel, joining two 1/4in PT male threads back to back. It screws into any 1/4in PT port and presents another 1/4in male thread on the far side, so it is the part you reach for when a hot or corrosive line has to be made up from threaded ports rather than push-in fittings.
This family is built past the point where push-in resin joints give up: working pressure to 1.0 MPa, proof pressure 3.0 MPa - three times the working ceiling - usable under vacuum down to -750 mmHg, and a temperature window of 0 to 150 C. The -S suffix replaces the family's usual nickel-plated finish with stainless 304 throughout, which is why this SKU shows up in wash-down plant, steam-adjacent lines and copper-free electronics or plating work. Use sealant on the PT taper threads; the fitting itself needs no torque figure and none is published.

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 BB0202-S Is Used
Plating and surface-treatment lines
Copper-free SUS304 keeps the 1/4in air and rinse lines around pickling tanks and electroplating jigs free of copper contamination, surviving splash zones where plated fittings would pit.
Commercial dishwashing and wash-down plant
On conveyor dishwashers and food-line rinse manifolds, the 1/4in PT both-male format bridges actuator ports to stainless headers while shrugging off daily caustic washdown at up to 150 C ambient.
Thermoformer vacuum and blow-off circuits
Rigid SUS304 joints on the 1/4in ports of vacuum cups and mould-cooling blow-off lines hold -750 mmHg vacuum and 1.0 MPa working pressure on the hot platen side where resin push-ins creep.
Is the Airtac BB Double Male Thread Straight Connector BB0202-S the Right Part?
Step down from 1/4in x 1/4in and the smallest mixed neighbour is BB0102-S territory - the 1/8in x 1/4in reducing male connector - or BB0101-S if both ports are 1/8in; expect a smaller through-bore and lower capacity feeding compact tools or sensor ports. Step up and BB0203-S gives 1/4in x 3/8in, with BB0303-S the all-3/8in equal pair; the larger thread suits mains-fed headers where a tighter bend radius matters less than flow headroom. If one of the two ports must stay female, the BD male-and-female family removes the need for a separate coupling nut; and if the second port is simply unused, an honest answer is the BZ plug rather than a connector capped with tape.
All threads in this series are PT taper - no NPT or G variants exist - so sealant choice should suit the Japanese PT form, not a parallel G.
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-S FAQ
It is a straight male connector with 1/4in PT male threads on both ends, body machined in SUS304 stainless steel. Working pressure is 0 to 1.0 MPa (0 to 10 kgf/cm2), negative pressure to -750 mmHg (10 Torr), proof pressure 3.0 MPa, and the permitted temperature range is 0 to 150 C. Ratings are identical to the nickel-plated BB0202; only the material changes.
Yes. The -S suffix changes the material to SUS304 only - dimensions, thread form and pressure figures all match the standard BB0202, so it drops straight into the same 1/4in PT port. Note the threads are PT taper, so apply thread sealant and tighten with a hex drive; AirTAC publishes no tightening torque for this family, so use good trade practice on a taper thread.
