Bsc Preferred 50092 Silicone Grease 1/2 Fl Oz

Product Description

The BSC PREFERRED 50092 is a 90% pure silicone grease formulated for use on rubber and synthetic O-rings in plumbing, HVAC, and mechanical systems. It contains no petroleum additives, making it safe for contact with rubber compounds that would degrade under hydrocarbon-based lubricants. The grease offers heat resistance up to 450 degrees F, exceeding the performance range of standard lithium-based greases. It is nonstaining, which makes it suitable for use in environments where residue or discoloration is a concern. The product comes in a 1/2 fl oz cup packaged in a blister card, sized for field use and service kit inclusion. Plumbers, HVAC technicians, and pool service professionals commonly carry this type of grease for routine O-ring service work.

This silicone grease is used wherever rubber or synthetic O-rings require lubrication during installation or replacement. Common applications include valve seats, pump seals, flare fittings, service port caps, and cartridge seals across residential and light commercial systems. Its petroleum-free formula makes it particularly appropriate for potable water applications where certain chemical contact restrictions apply. The 1/2 fl oz size is well suited for individual service calls and small-volume maintenance tasks.

Compatibility

Designed for use with rubber and synthetic O-rings across plumbing, HVAC, and mechanical service applications where a petroleum-free silicone lubricant is required.

Installation Notes

Apply a thin, even coat of grease to the O-ring surface before seating it in the groove or fitting. Shut off water supply or system pressure before servicing any valve, pump, or fitting. Avoid overapplication, as excess grease can attract debris and compromise the seal. This product is intended for use by licensed plumbers, HVAC technicians, and qualified service professionals following applicable local codes.
