SKF 226402 Adapter block, Max Pressure 400 MPa

• Quick action locking screw
• Adapter block
• Telescopic steel bar

The adapter block can also easily be locked on the top of a working bench by means of a standard G-clamp. It can also be clamped in a vice.

Screw the oil injector on the adapter block until the thread can be seen in the inside slot.

Screw the rectangular gauge adapter nipple into the thread of the pressure gauge tightly, so that a good seal is formed. Make sure the flat surfaces of the nipple are aligned with the pressure gauge.

The use of a vice, with soft aluminium jaws, can greatly simplify the mounting of the pressure gauge.

This nipple will remain on the gauge. There is no need to remove the gauge from the nipple after using the equipment.

Push the gauge adapter nipple into the top slot of the adapter block.

Note: To avoid misalignment the O-ring has to be located on the flat part of the gauge nipple.
The O-ring has no sealing function, it only helps in aligning the components. 

The following operation should be done carefully. The illustration shows how the seal will be achieved. Screw the high pressure pipe nipple into the back of the adapter block, while gently moving the gauge adapter nipple in order to secure the correct position of the high pressure sealing area.

Then screw the oil injector into the block until it is touching the gauge nipple. Gently loosen and tighten the pipe and oil injector until the oil injector is in the correct position, then tighten the high pressure pipe.

Make sure all parts are properly aligned. Failure in doing so will prevent proper sealing and will cause leakage. The component design helps achieve an effective sealing with a moderate tightening torque.
