All our kits use only high density Aluminosilicate glass, quality Ruby Mica, graphite gaskets and 316 stainless steel covers. This provides a very high quality product that is equal to or better than the OEM parts. Drumline endeavours to maintain a stock of every kit, and at very competitive prices.

KIT CONTENTS

Each kit contains 1 x high density Aluminosilicate glass, 1 x stainless steel glass cover, 1 x ruby mica protective disc, 2 x graphite gaskets.

 

HIGH DENSITY ALUMINOSILICATE GLASS

Aluminosilicate glass comes in different densities. Always ensure that you supplier can prove the density of the glass used in their kits. Standard density glass is cheaper and weaker.

Aluminosilicate glass may be used:

• in applications with saturated steam or in an alkaline medium:
  • maximum operating temperature - up to 400 °C
  • maximum working pressure - up to 220 bar
  • Used in conjunction with Mica sheild for gauge glass applications



GASKETS

Drumline uses high quality graphite gaskets in all its kits. Graphite gaskets ensure a better and more forgiving seal over metal or paper gaskets.

MICA

Drumline uses Indian Ruby mica protective discs in all port kits
