Hylogrip HY5172 thread sealant may be used as a sealing and locking compound on all types of pipe threads. The product is superior to P.T.F.E. tape, which can become detached and cause operating problems in control systems requiring a high level of particulate cleanliness. Hylogrip HY5172 has proved extremely effective on stainless steel pipe threads, operating successfully where other compounds of this type have failed to perform satisfactorily. This makes them particularly useful in the construction of hydraulic control systems for the offshore industry, where stainless steel pipework and components are widely used and joint integrity is vital. Because the compound cures within the joint, it not only prevents leakage from within the pipework, but also excludes the surrounding environment from the joint surface. This helps to reduce the likelihood of crevice corrosion taking place, especially where the joint is immersed in sea water.
