Tank & Manlid Sealing

2008_09300014webQuality and longevity of seal performance is a key consideration when choosing these products for two main reasons

  1. Cross-contamination between batches of chemicals
  2. Environmental issues caused through leaks and contamination

Traditionally, braided gland packing and rubber gaskets have been widely used in the chemical and tank farm industries. Whilst these are available at a lower cost, their impact on product quality and overall poor seal life raises the question of true life product cycle cost.

We supply a range of products that have near universal chemical resistance, with the exception of some alkali metals, Fluorine and some rare fluorinated and complex halogen compounds. Depending on tanklid design, they can be used within the temperature range from -60 and +205 degrees Celsius and pressures up to 6 Bar.
