Super Lube 56204 O-Ring Silicone Lubricant, 4 oz Bottle (Pack of 3)

This 3-pack contains three 4 oz bottles of Super Lube 56204 O-Ring Silicone Lubricant, the same clear, non-curing silicone fluid as the single bottle. It is aimed at people who service seals for a living or across several sites: pool service routes (pump lids and filter seals), plumbers and water-treatment technicians (faucet valves and water softener valves), pneumatic maintenance shops, and food plants that want an H1-registered O-ring lubricant at every line. Keeping a bottle in each van or toolbag beats sharing one.

Key features

• Three 4 oz bottles of part number 56204
• 5,000 cSt silicone fluid that helps O-rings seat and protects them from pinching and cutting during assembly
• -58°F to 392°F (-50°C to 200°C); waterproof; dielectric strength 18 kV/mm
• Rated excellent with EPDM, nitrile, FKM/Viton, neoprene, butyl, natural rubber, PVC, nylon and polycarbonate
• NSF H1 (#156449), Kosher

Where to use it

Static and dynamic O-rings, pressure plug valves, pneumatic systems, pool pump and filter seals, water softener and faucet valves, rubber gaskets and weather stripping. In vacuum systems it helps lower the leak rate by filling the imperfections in gland surfaces.

How to use

1. Clean the O-ring, groove and mating surfaces.
2. Apply evenly; a thin film is enough to seat the ring.
3. Recap each bottle after use to keep grit out, and store spares in their original containers.

Compatibility and cautions

Not compatible with silicone rubber (VMQ and related types); POM (Delrin) and PPS rate good. H1 registration is for incidental food contact and is not a drinking-water component certification, so follow the filter or valve maker’s lubricant specification. Read the SDS before use.

Choosing between the 3-pack, the single bottle and O-ring grease

Occasional users only need the single 56204 bottle. If you need a paste that stays on vertical or large seals, choose Super Lube 93016 O-Ring Silicone Grease in a 14.1 oz canister. For general rubber and plastic lubrication with a thinner fluid, see Super Lube 56104 Silicone Oil 100 cSt.
