Caution
To prevent Product damage or damage to a gauge:
• To prevent incorrect sealing that creates an unsafe condition, do not use thread-
sealing tape or any other sealing method on the DUT or the adapters. The Gauge
Adapter sealing system can be hand-tight sealed up to 70 MPa (10500 psi).
Wrenches or similar tools are not required. Over tightening can cause damage to
threads or sealing faces.
• Before connection, ensure that there are O-rings fitted to the test port and gauge
adapter.
• Check that the sealing face of the device to be fitted is clean and undamaged, as
scratches or dents can form leak-paths.
To connect the DUT:
1. Select the appropriate adapter from the adapter set to match the thread on the DUT.
2. Screw the adapter fully onto the DUT so that the bottom face of the DUT seals on the O-
ring inside the adapter. Hand-tight is sufficient.
3. Turn the adapter collar counter-clockwise until the adapter seals on the O-ring in the
mounting post to mount the DUT/adapter assembly to the test port. Hand-tight is
sufficient.
4. To adjust the position of the DUT, hold the adapter, and turn the collar clockwise 1/4-turn.
5. Position the DUT to face the desired direction, and turn the collar counter-clockwise to re-
seal.
