The standard kit consists of:
- One sealing gasket, fabricated from PTFE material, 3 mm thickness, for isolating and sealing between the two flanges of the joint
- Same number as the number of bolts – isolating adapter sleeve for isolating between the bolts and the flanges’ material, fabricated from PTFE material
- Double number of bolts (2 pieces for each bolt) – isolating washer for isolating between the flanges and epoxy fiber glass manufactured nuts, 2 mm thickness
- Double number of bolts (2 for each bolt) – metal washer
Upon request, we can manufacture other isolating and sealing materials (with or without rubber rings)
