Standard oil seal Barrier

Typical Oil Seal Barrier

An oil seal barrier may be fitted to any Thermocouple or RTD extension cable to prevent the loss of low pressure oil or liquids escaping between the insulation material and the conductor wires.

The oil Seal barrier can also be used to seal the assembly where it passes through a casing.

A range of sizes are available from 50 to 65mm in length and from 2 to 6.4mm in Dia.

 

Note: The standard OIL SEAL BARRIER is 65mm long x 5.5mm diameter as above, subject to cable diameter.

For non-standard diameters and/or lengths, use order reference below and add length in mm to order reference, e.g. OB60 - 50 = 6.0mm dia. x 50mm long.

The table below may be used as a guide for compatibility of RTD extension cables with Oil Seal Barrier diameters and probe diameters.

Test pressure up to 5 bar @ ambient temperature.
