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.

These sealants include a material certificate with traceable lot number, test report, and product shelf life. They’re non-sagging, so they won't drip from vertical and overhead surfaces. Made from silicone rubber, sealants are RTV (room-temperature vulcanizing).

Elongation indicates flexibility—the higher the value is, the more a sealant can stretch. These sealants are best suited to joints between similar materials that aren't exposed to wide temperature fluctuation.

Completely free of oil and chemically inert, these sealants are safe to use with wet and dry oxygen systems. They contain PTFE, which provides a slippery surface that keeps threads from binding. These sealants are non-hardening, remaining pliable enough to self-heal and stop leaks before they start, so they’re often used in high-vibration applications that could cause standard thread sealants to fail. Since they have low locking strength, these sealants can be adjusted without tools.

Take your time positioning parts—these epoxies remain adjustable for at least 90 minutes before setting. Epoxies are the strongest and most chemical-resistant structural adhesives. They bond especially well on metal.

These adhesives come in two parts that need to be mixed. The container size listed is the combined total of the two parts.

To speed cure time on coated fasteners, aluminum, stainless steel, or titanium, apply these adhesive primers before using threadlocker or retaining compound. They also work with no-mix acrylic adhesives.

Because this expanded PTFE tape is thicker than other gasket tape, it fills the irregularities on rough-surfaced flanges when compressed for a tight seal. This gasket tape is chemically inert, except to molten alkali metal and elemental fluorine.

In addition to being waterproof, this glue is made of FDA listed materials. It bonds soft and hard woods, and can be sanded and painted after reaching full strength.
