Sur-Seal Inc.

Sur-Seal Inc. 7530 Virgin PTFE (polytetrafluoroethylene) is a high molecular weight polymer and one of the most versatile plastics known to man. Sur-Seal Inc. 7530 Virgin PTFE sheet can handle virtually all chemicals in the 0-14 pH range with the exception of molten alkali metals and elemental fluorine. It is suitable for service at temperatures from the cryogenic range up to 500°F.

TEADIT® 24B is made from 100% pure, expanded, virgin PTFE. The whole production process is subject to strict quality control, registered under DIN EN ISO 9001. Because of the excellent thermal and chemical resistance of TEADIT® 24B, it can be used in a wide variety of static applications in nearly all kinds of industry. The exceptional malleability of expanded PTFE can compensate for out-of-parallel andor damaged sealing surfaces and allows use with stress sensitive connections and applications where only a limited flange load is available, e.g. plastic flanges, glass flanges, etc. Typical applications are the sealing of flanges, pump housings, compressors, hand- and manholes, air ducts, compensators, heat exchangers and many more.

• Inner Diameter:17/23 (0.739) Inches (1cm 8.77mm)
• Outer Diameter:29/33 (0.879) Inches (2cm 2.33mm)
• Cross Section4/57 (0.07) Inches (1.78mm)

SPIRAL WOUND Teadit Spiral Wound Gaskets are for applications with high temperature variations (thermal cycling), andor pressure variations, andor flange rotation problems etc., gaskets with adequate residual stress (stress retention), flexibility and recovery are needed. They have been designed to meet these demanding requirements. Spiral-wound gaskets are made of a preformed metallic strip and a soft filler material, wound together under pressure, and optionally with an inner andor outer guide ring. The metal strip holds the filler, resulting in excellent mechanical resistance, resilience and recovery. Centering ring accurately locates the gasket on the flange face, provides additional radial strength, and acts as a compression limiter Spiral winding (sealing element) consists of metal and soft filler material Durable, easy installation and removal

Style NA1088 is a high density, controlled swell sheet gasket material with a proprietary binder & reinforced with a syntheticinorganic fiber blend. It is designed for demanding applications requiring excellent sealablity, torque retention, recovery, and conformability to uneven flange surfaces. The material provides a controlled swell in the presence of oils, fuels, lubricants, and watercoolant. It is used in heavy duty & industrial oil sealing applications such as diesel engine oil pans and front covers, compressors, generators, pumps, valves, gear boxes & housings, transformer, sight glass, manhand-hole covers. The following specification values are for 0.8mm (0.031”) gauge material.

Style 2003 is an interlock braided packing, using pure PTFE yarn, reinforced with aramid corners. The yarns are pretreated with PTFE dispersion, plus a break-in lubricant to reduce the coefficient of friction, as well as the frictional heat created by high shaft speeds. Style 2003 packing, with its unique combination of PTFE and aramid fibers, is dimensionally stable, non-contaminating, has excellent lubricating and running characteristics, and because of the aramid corners, is very wear resistant. It handles acids, alkalis, and a broad range of chemicals. It is well suited for service in rotary and reciprocating pumps, mixers, agitators and reactors, especially where abrasive wear is a problem.
