Lubricants and Sealants

Audco and Nordstrom Lubricants and Sealants are high viscosity fluids, specially produced to seal and lubricate plug valves. Only Audco and Nordstrom Sealants should be used on Super-H plug valve, the use of sealant or commercial greases not recommended by us can impair the functioning of the valve and it the worst case seize it completely.

Furthermore with minimal sealant injection frequency can guarantee zero leakage seal and smooth operation on Super-H plug valve.
Moreover Audco and Nordstrom Sealant supplement "Super LoMu" treatment to reduce friction between the seating surfaces and provide a very effective seal, even at higher line pressure.
Sealant should be selected based on working fluid and operating temperature. The tables below summarise our general sealant recommendations.
