Spiral Wound Gasket - Style ‘G’:

Outer and Inner diameters are reinforced with minimum 3 plies of metal without filler to give greater stability and better compression characteristics.
No inner or Outer rings, used in thousands of different applications, they may be furnished in many different sizes and thicknesses.
Style - G are made in standard sizes to fit:

1. Large tongue and groove joints, 1/2” thru 24” NPS, standard pressures

2. Small tongue and groove joints, 1/2” thru 24” NPS, standard pressures

3. Large male and female joints 1/4” thru 24” NPS, standard pressures

Spiral wound gaskets must be sized to ensure the spiral-wound component is seated between flat surfaces. If it protrudes beyond a raised face or into a flange bore, mechanical damage and leakage may occur.
