AGIS, LLC is a manufacturer and distributor of a wide range of boiler gaskets as well as a variety of other heat-resistant specialty products for industrial and marine applications.

AGIS boiler gaskets include:


Specially formulated rubber gaskets molded to exact shape and size of the manhole or handhole of your boiler, water heater or air tank. Suitable for temps to 380 . F and pressures to 180 PSI. Resistant to boiler treatment chemicals. Available in standard, oval, obround, pear, round and diamond shape. Custom shapes and sizes on request. 

Topog-E®: 2000 High Pressure Boiler Gaskets

A cost-effective sealing alternative to spiral wound gaskets in most types of higher pressure industrial vessels and tanks with inspection openings. Manufactured from multiple layers of graphite foil and reinforced with 316 stainless steel foil for added stability, Series 2000 gaskets offer exceptional thermal stability, chemical inertness, light weight and compressibility.

Service: temps to 1200 F (650 C) in steam; to 850 F (454 C) in atmosphere; pressure (typical): 250 - 2000 psi (17-138 bar)


Manufactured from EPDM, a special rubber formulation with excellent resistance to heat, chemicals and ageing. Performs well in most steam and water sealing applications where temps and pressures do not exceed 375 and 150 PSI respectively. Extreme resiliency enables AGIS gaskets to fill uneven spots on flange surfaces for superior seals.


Manufactured from a unique blend of carded wire-inserted fiberglass and proprietary fibers, coated with heat-resistant rubber compound. Rated at temps to 380 . F and pressures to 180 PSI. Brass wire inserted throughout fabric ensures greater heat dispersion. No taped joints to impede performance. Available in manhole or handhole; round, oval and obround shapes.


Manufactured of layers of preformed 304SS metal strip (for mechanical resistance) and intermittent layers of micarb sealing paper (for resiliency). Material is wound on forms to specific shape and size. Ends are then welded. Rated to 999 PSI and temps to 1000 (1999 PSI available) For extreme temperatures, a graphic filler can be used. Standard shapes available: oval, obround, pear, diamond, round, square. Suitable for boilers where pressures exceed non-metallic gasket capabilities 


Made of 100% virgin, expanded PTFE, AGIS PTFE joint sealant is a soft, compressible form-in-place gasket material that conforms to almost any sealing surface-- even rough, scratched, and damaged surfaces. Suitable for boiler & pressure vessel manholes & handholes. Upon compression, it forms a thin, hard seal capable of withstanding a wide range of pressures, temperatures and chemical attacks. FDA compliant. East installation, easy removal. Service conditions: temperatures: -450°F  to 600° F, F.V. to 3000 psi.  Sizes: 1/8" to 1" width; 15' to 150' lengths Custom sizes and shapes available.


AGIS boiler gaskets are employed by virtually every industry throughout the world, including chemical processing, petroleum, waste/water treatment, steel & mining, food processing, plant maintenance, power generation, metals/heat treating, transportation and marine, pulp & paper manufacturing, to name a few.
