Industrial Silicone Multi-Purpose Lubricant - 4oz Brush Top
SKU: LTSL-4
Industrial Silicone Grease & Lubricant – 4 oz Brush-Top Jar
One jar, endless protection—waterproof, dielectric, food-grade safe
From squeaky O-rings to corroded trailer plugs, a quality silicone grease is the secret weapon pro mechanics and gearheads trust to waterproof, lubricate, and insulate where petroleum greases fail. Our 4 oz brush-top jar delivers a crystal-clear, high-purity silicone lubricant that stays put from sub-zero storage yards to 400 °F engine bays. Whether you service brake caliper slide pins, rebuild pool pumps, or seal electrical gaskets, this single compound keeps rubber supple, threads smooth, and moisture permanently locked out.
Why choose silicone grease instead of “general-purpose” lubricants?
Petroleum grease swells rubber, dissolves plastics, and burns off at modest heat. By contrast, our industrial-grade silicone lubricant:
-
Wipes away water — 100 % hydrophobic barrier blocks rust and dielectric creep.
-
Survives -40 °F → 400 °F — never hardens in winter, never drips off exhaust hangers.
-
Non-conductive — dielectric strength > 25 kV/mm protects sensors and ignition boots.
-
Rubber & plastic friendly — safe on EPDM seals, PVC fittings, polycarbonate light housings, and more.
Bottom line: one thin coat today costs pennies, but it can save hours of seized-part headaches tomorrow.
What’s inside the jar
-
4 oz (118 mL) clear silicone grease – enough to service hundreds of seals.
-
Built-in natural-bristle brush for clean, controlled application—no mess, no lost caps.
-
Quick-reference torque & compatibility guide printed under the lid for shop-floor convenience.
Where silicone grease shines (and where it doesn’t)
| Application | Why it works | Pro tip |
|---|---|---|
| O-rings & gaskets | Maintains elasticity, stops dry-rot | Light smear—excess attracts dust |
| Spark-plug boots & coil packs | Prevents arcing, eases removal | Pair with our [dielectric grease](/products/dielectric-grease-4oz-brush-top) for full ignition service |
| Brake caliper slide pins | Water-proofs without swelling rubber boots | Clean old grease first; reapply every pad change |
| Marine battery lugs & trailer plugs | Blocks salt spray & galvanic corrosion | Coat threads, then wipe visible excess |
| Pool & spa pump seals | NSF H1 rating means safe around treated water | Re-grease at spring opening |
| Do NOT use on | Wheel-stud seating cones, high-pressure oxygen lines | Choose our [anti-seize lubricant](/products/industrial-anti-seize-lubricant-4oz-brush-top) or oxygen-safe grease instead |
Three-step application—takes less than 60 seconds
-
Clean & dry the surface; remove old grease or corrosion.
-
Brush on a paper-thin film of silicone grease—a little goes far.
-
Assemble & wipe away squeeze-out for a factory-clean look.
Tech tip: A toothbrush-sized dabber lets you reach tight EV battery connectors or scuba O-rings without over-greasing.

good for making things very slick. I bought it to use on rc servo gears, but good for many things.
I use this on my seal around my sunroof and my Crosstrek and also on my daughter's Subaru Impreza also around the door jambs that are all rubber this helps to keep them nice and soft good product The only thing was the brush they give you falls apart
First time using this, and I am impressed, there is a brush built into the lid you put the lubricant on the brush and then apply it to the part that needs lubricating. This silicone lubricant is a lot better than the liquid lubricants as the liquid will run all over whereas this is more like a grease substance/paste and will not run all over, it says in place where it is brushed onto! This silicone lubricant is better than grease and seems to last longer than grease as well.
Good grease used it the past weekend on my truck that had some rough looking bolts with some surface rust build up cleaned them up a bit and used this grease to help keep them good and the grease is thick and the cap has the brush to apply the grease which is good.
This stuff is nice and thick and sticks to whatever you apply it to. since its silicone based it is super slippery. it does not have that pungent acrid smell that the usual caulking style silicone has, this stuff has nearly no smell at all which is nice. I have been using this stuff on electric fan motor shafts and it is working really great. since its thick, it stays in place like what you would expect from a heavy duty bearing grease would, but this stuff provides better lubrication than grease does. I had never heard of this stuff before, but now that I have tried it, I am not going to be going back to the old greases that I used to use.
