About the Airtac BZ External Hex Plug BZ01
The BZ01 is a hexagon head cap plug: a single male 1/8in PT thread with a hex head and nothing on the other end. Its one job is to close an unused port for good, which makes it the smallest and simplest part in AirTAC's nickel-plated pipe joint family.
Because it belongs to the same profile as the BB, BD and BU connectors, it carries figures a push-in resin plug cannot offer: 0-1.0 MPa working pressure, -750 mmHg vacuum, 3.0 MPa proof pressure and a 0 to 150 C temperature rating. That is why the BZ01 is the part to reach for when a spare tapping sits near a hot surface and a plastic plug would soften or creep.

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 BZ External Hex Plug BZ01 Is Used
Manifold spare port on moulding tools
Close the spare gauge tapping on a pneumatic valve manifold mounted beside a plastics injection mould, where the 150 C body rating outlasts a nylon plug.
Receiver drain tapping near dryers
Blank the unused bottom drain tapping of a compressor air receiver feeding a drying oven line, keeping the 3.0 MPa proof margin in reserve.
Wash-down valve island port
Seal an odd 1/8in port on a wash-down conveyor's valve island where an open tapping would trap water and cleaning chemicals.
Is the Airtac BZ External Hex Plug BZ01 the Right Part?
BZ01 is the bottom of the BZ ladder, so the only real alternative within the series is the next size up, BZ02 (1/4in PT); there is no smaller plug below 1/8in. If the port may be needed again later, a threaded valve or gauge in 1/8in is a better answer than a blank.
If you actually want a live connection rather than a blank, stay inside the same 1/8in thread family: BB0101 gives a male-male joiner, BU0101 a female-female joiner, and BD0102 steps 1/8in female down to 1/4in male without an extra adapter. The BZ01 is the honest choice only when the port should stay sealed.
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 BZ External Hex Plug BZ01 FAQ
BZ01 is a hexagon head cap plug with a single 1/8in PT male thread. Working pressure is 0-1.0 MPa (0-10 kgf/cm2), vacuum capability is -750 mmHg (10 Torr), proof pressure is 3.0 MPa, and the rated temperature range is 0 to 150 C. The body is nickel plated.
PT is a taper thread, so the seal is made on the thread flanks; apply PTFE seal tape or an approved thread sealant to the male thread before wrenching it home on the hex flats. AirTAC does not publish a tightening torque for this part, so tighten to a sound metal-to-metal seating rather than to a stated figure, and confirm the sealant's own temperature rating if the port runs hot.
