Glass Fibre Rope Seals

Product Description

PYROSEAL glass fibre rope seals are manufactured from continuous filament ‘E’ type glass yarns which have been mechanically bulked to increase the loft. ‘E’ type glass fibre offers the best thermal resistance of the types available and the bulking process creates an end product which is light in weight yet still very efficient as an insulator. The basic fibres are lightweight, resilient, incombustible and possess a high degree of mechanical strength.

PYROSEAL glass fibre rope seals are suitable for operation in temperatures up to 600ºC depending upon the particular application.

PGS.10 seals are constructed from a thick glass yarn wall coupled with a stranded centre glass yarn core; giving it a firm compression. 

PGS.11 seals are constructed as a thick glass fibre rope seal without the addition of central filler yarns. This process results in a lightweight and extremely flexible seal which is able to conform to tight radii without the loss of section or performance. 

These seals possess excellent handling and flexibility characteristics and are ideal for use in dry, static sealing applications involving hot air and combustion gases.

PYROSEAL’s are resistant to oils, most chemicals and solvents and is unaffected by bacterial growth.
