coated probe covers

fep heat shrinkable probe covers

FEP heat shrinkable probe covers present a complete chemical resistance and non-stick properties with an easy shrink on sleeve.


FEP heat shrinkable probe covers offer the best all round material and shrink properties. They can be easily shrunk into place at 110°C, yet have a working temperature of 200°C.

The total chemical resistance offered by these probe covers make them attractive for universal applications, allowing stocking of only one type of probe that can be used for all environments.

We stock a range of standard sizes of FEP heat shrinkable probe covers, from 2.80mm to 16mm diameter. Find our FEP Probe Cover Sizes. However we understand that all our customers' applications have different requirements and so we can produce custom sizes.

Chemical Etching Service

If necessary, the boots can be supplied with the inside surface chemically etched so that the FEP probe cover can be bonded to the surface of the probe, although normally this is not necessary.
