Why Use TOPOG-E?
Why Use TOPOG-E
A Heritage Steam boiler can make extreme demands on gaskets. Topog-E moulded rubber gaskets are specifically formulated to meet and exceed these demands and deliver an exceptional performance.
Topog-E gaskets have been refined through a series of over 600 research formulation tests to ensure that they are able to meet the exacting performance standards expecting by the heritage steam movement.
Conforms : to the topography of the mating surfaces
Withstands : a boilers full, continuous and cycling operating pressures.
Continuous exposure to water treatment chemicals.
Continuous exposure to ion and oxygen in hot air.
Prevents : all leakage.
Replaces easily : without chiselling or buffing.
When used on steam pressure vessels Topog-E gaskets are typically used at operating pressures of up to 180 PSI (12 Bar) and saturated steam temperatures of 380°F (193°C) for an average service life of one year.
When used in other applications Topog-E gaskets are sometimes used at pressures above 200 PSI (14 Bar) where temperatures are typically more moderate (eg. below 250°F/121°C).
Topog-E gaskets have been used successfully around the world for over forty years. In general any type of industrial pressure vessel or tank that has inspection openings is a potential application where Topog-E gaskets can be used as a cost effective sealing device.
The Topog-E gasket company formulates and mixes its own rubber invests heavily in research and development efforts to insure that Topog-E gaskets live up to their worldwide reputation for quality, durability and ease of use.
Topog-E gaskets are tested in house at steam pressures and temperatures far exceeding the 180psi and 380°F levels below which most Topog-E gaskets are used in steam applications. Carefully installed and monitored Topog-E gaskets are routinely subjected for extended periods of time to steam pressures and temperatures of up to 360 PSI (26 Bar) and 438°F (226°C)
Expected Life in Steam Boiler Applications
The following table was prepared, based on actual customer use and extensive testing to be used as a general guide for estimating approximate service life for properly installed Topog-E gaskets in steam pressure vessels.

Installation Environment & Suitability
Topog-E gaskets are specifically formulated to have excellent resistance to steam as well as hot and cold water.
They also have a good resistance to:
- Phosphate esters
- Silicone oils & greases
- Ammonia Animal and Vegetable fats
- Selected refrigerants
- Dilute Acids
Water treatment chemicals when used in accordance with supplier's guidelines should not have a significant effect on the service life of a properly installed Topog-E gaskets.
