The AirTAC Airtac POC Round Thread Straight Connector POC1202 is a genuine male connector (compact) for push-in tube connection, rated 0 - 1.0 MPa (0 - 10 kgf/cm2) with a 1.5 MPa proof pressure.
The POC1202 is AirTAC's compact male connector from the POC one-touch family: a Dia 12 mm tube lands on a 1/4in PT male thread with the shortest body the series offers. Push the tube straight into the chuck and the stainless spring gasket grips it for a pressure-tight seal; press the POM release ring and the tube slides straight back out. The thread arrives with sealant pre-applied, so it goes onto the port without extra tape or compound.
This is the resin/brass spec profile: 0-1.0 MPa working pressure, -750 mmHg vacuum, 1.5 MPa proof pressure, and -20 to +70 C with soft nylon or polyurethane tubing. The body is PBT with a brass stud, the chuck and button are POM, and the O-ring is NBR. Standard finish is grey; the D suffix variant changes only the release button colour, not the body.

Stepping down from a filter-regulator-lubricator with a 1/4in outlet to a 12 mm nylon trunk line feeding a machine's air ring main, where the compact POC body clears adjacent gauge and switch connections.
Feeding the large-bore advance cylinder of a carton sealing head, where a 12 mm supply line keeps pressure drop low on a fast double-acting stroke and the short body fits the recessed port.
Supplying vacuum ejectors or gripper actuators on a palletiser cell, where 12 mm tubing carries the volume several ejectors need and the push-fit release allows quick gripper swaps during changeover.
Dia 12 is the top of the tube ladder on a 1/4in POC thread, so the only step down that exists is Dia 10 (POC1002) - a smaller bore with visibly lower conveying capacity through the same fitting outline. There is no Dia 16 in this catalogue; when a line needs more bore than 12 mm, the circuit has to be split or re-planned rather than upsized here. Note also that a 12 mm tube cannot be paired with a 1/8in POC thread at all: the 1/8in ladder tops out at Dia 10, so this tube size is served by 1/4in, 3/8in or 1/2in threads only.
Match the thread to the port before ordering: 1/4in suits cylinder ports and valve manifolds, while 3/8in (POC1203) or 1/2in (POC1204) suit larger FRL outlets and longer ring mains. If the fitting must pass through a panel or enclosure wall instead of screwing onto a port, the bulkhead-style PMF family in Dia 12 (locknut thread M22x1) is the correct shape, not this connector.
Quick checklist
It is a compact one-touch male connector for Dia 12 mm tube on a 1/4in PT male thread. Working pressure 0-1.0 MPa (0-10 kgf/cm2), negative pressure down to -750 mmHg (10 Torr), proof pressure 1.5 MPa, operating temperature -20 to +70 C with soft nylon or polyurethane tubing. Body PBT with brass stud, POM chuck and release button, NBR seal, standard colour grey. Thread sealant is applied at the factory.
The chuck is sized to one exact tube OD, so it holds only 12 mm tube - a 10 mm tube will not seal here, and imperial 1/2in tube will not fit at all. On the thread side, AirTAC lists 12 mm tube on the POC series only in 1/4in, 3/8in and 1/2in PT; the 1/8in size stops at Dia 10. Pick POC1203 or POC1204 if the port is larger, or POC1002 to step the line down to a 10 mm bore.
