5. QUICK CONNECTORS WITH EXPANDABLE JOINTS
ATEQ quick connectors designed to be used manually or integrated into the leak tester’s fixture.
They connect the leak tester to your part reliably and assure leak tightness. Several connectors
may be connected to the same manifold, piloted by an ATEQ, a PLC or manually.
They easily adapt to a large number of fittings and opening of varied dimensions. Their use
ensures that non-machined walls can be guaranteed airtight.
There are 4 basic versions of the ATEQ quick connectors:
9 SA for external connections,
9 SI for internal connections,
9 SAG and SIG for internal and external threads.
They come black anodized with engraved markings. Different types of seals are available
depending on the requirements.
5.1. O
PERATION
The connector is positioned manually, automatically or using cylinder.
Compressed air goes through the pilot port via a three way valve. The pressure pushes the
piston which compresses the seal. The air tightness is therefore ensured.
5.2. STANDARD DIMENSIONS
SAG and SIG have been designed for internal and external threads. For the time being, they
are available in the following sizes: 1/2", 3/4", 1", 11/4", 11/2", 2", BSP.
The SA and SI are designed for internal and external tubes/bore with dimensions from 3 to 80
mm for the external diameters (SA), and from 10 to 75 mm for internal diameters (SI).
