Coolant-Resistant Surface Fillers

Repair small leaks and cracks in coolant systems for commercial vehicles and industrial equipment. These surface fillers meet ASTM D3147 for their ability to stop leaks in engine cooling systems. Pour them into your coolant to fix both internal and external leaks. They contain ceramic microfibers and copper particles to create a permanent seal. They’re compatible with antifreeze and other coolant system additives.

Structural Sealants


These structural sealants combine the mechanical strength of an adhesive with excellent sealing properties and high flexibility. They’re non-sagging, so they won't drip from vertical and overhead surfaces.
Elongation and joint compression/expansion tolerance indicate flexibility—the higher the values are, the more joint movement sealants can sustain. For joints between dissimilar materials and in environments with wide temperature fluctuation, choose a sealant with a higher elongation or joint compression/expansion tolerance. For high-wear applications, choose a harder sealant for the most abrasion resistance.

Puncture-Resistant Sealants


Form seals that resist punctures, cuts, and abrasion to withstand heavy wear and tampering. These sealants are non-sagging, so they won't drip from vertical and overhead surfaces.
Elongation and joint compression/expansion tolerance indicate flexibility—the higher the values are, the more joint movement sealants can sustain. These sealants are best suited to joints between similar materials that aren't exposed to wide temperature fluctuation.

Structural Oil- and Fuel-Resistant Sealants


Impervious to the swelling effects of oils, fuels, and solvents, use this high-strength silicone sealant to assemble and repair fuel systems and tanks. Silicone forms a tough, rubbery, UV-resistant seal that remains flexible over time. It's non-sagging, so it won't drip from vertical and overhead surfaces. Also known as RTV (room-temperature vulcanizing).
Elongation and joint expansion/compression tolerance indicate flexibility—the higher the values are, the more joint movement sealants can sustain. This sealant is best suited to joints between similar materials that aren't exposed to wide temperature fluctuation.

High-Strength Concrete Joint Sealants


Seal concrete joints in high-traffic areas—these sealants stand up to heavy wear and tear, such as steel wheel traffic. They're non-sagging, so they won't drip from vertical and overhead surfaces. Made from silicone, sealants are RTV (room-temperature vulcanizing).
Elongation and joint compression/expansion tolerance indicate flexibility—the higher the values are, the more joint movement sealants can sustain. These sealants are best suited to joints between similar materials that aren't exposed to wide temperature fluctuation.

Non-Hardening Thread Sealants



Often used in high-vibration applications that could cause standard thread sealants to fail, these never fully harden and remain pliable enough to self-heal and stop leaks before they start. Formulated without PTFE, these sealants are less slippery and less likely to result in overtightenting than sealants that have PTFE, making them good for plastic pipe where overtightening could lead to cracks and breaks. They have low locking strength, so they can be adjusted without tools.
To adhere to safety standards for drinking water systems, use sealants that meet NSF/ANSI 61.
Sealants that cannot be sold to the listed regions are restricted due to local VOC (Volatile Organic Compounds) regulations.

Glue-on-a-Roll

Apply this glue-like tape for a no-mess alternative to liquid adhesives, hot melts, and staples. Also known as adhesive transfer tape, these rolls have a thin film of pressure-sensitive glue on a peel-away liner. They are thinner and more conformable than tape with adhesive on both sides.
9482PC and 9485PC are a good choice for precise applications, even on slippery plastics. They're reinforced with fiber so they keep their shape and don’t ooze out, unlike softer adhesives.
