SS 304 with PTFE filler spiral wound gasket from Kaxite Sealing is a CGI-style semi-metallic gasket made with SS 304 / UNS S30400 V-shape winding and PTFE soft filler, complete with inner and outer rings. The PTFE filler provides excellent chemical resistance against most acids, alkalis, organic acids, inorganic acids and solvents, while the SS 304 winding delivers strength, spring-back and reliable sealing. Suitable for flat face and raised face flanges, high-pressure service and corrosive or toxic media. Available in ASME B16.20 dimensions, custom sizes, OEM private-label packaging and bulk quotations for B2B buyers. Send NPS, pressure class, filler, ring material, quantity and destination port for a firm quote.

SS 347 vermiculite spiral wound gasket from Kaxite Sealing is manufactured with UNS S34700 stabilized stainless steel winding and vermiculite filler for 427–816°C service. The niobium-stabilized 347 grade resists intergranular corrosion and polythionic acid stress corrosion cracking in refinery, petrochemical and high-temperature oxidizing service. Available in ASME B16.20 CG, CGI and flange-facing constructions, with carbon steel or stainless steel outer/inner rings. Custom sizes, OEM private-label packaging and bulk quotations for B2B buyers. Send NPS, pressure class, filler, ring material, quantity and destination port for a firm quote.

Kaxite Sealing is a China-based SS 304 CG spiral wound gasket manufacturer, producing gaskets from SS 304 stainless steel winding with an outer guide ring only — the CG configuration per ASME B16.20. SS 304 is the most common form of stainless steel used around the world due to its excellent corrosion resistance and value. It can withstand corrosion from most oxidizing acids, and its durability makes it easy to sanitize — ideal for kitchen, food and general industrial applications. The basic steel alloy composition is 18% chromium and 8% nickel, with carbon, manganese, silicon, phosphorus and sulfur making up the balance. This gives SS 304 a well-balanced combination of weldability, corrosion resistance and oxidation resistance. Chemical composition: UNS S30400, Cr 18–20%, Ni 8–10.5%, C ≤0.08%, Mn ≤2%, Si ≤0.75%, P ≤0.045%, S ≤0.03%. Mechanical properties: tensile 550 MPa, yield 230 MPa, elongation 51%, density 7.93 g/cm³, hardness 85 HRB. The CG style carries an outer guide ring but no inner ring, and is suitable for male and female pipe flanges. Very suitable for flat bottom groove flanges, natural gas and power generation, hydrocarbon processing and refining, petrochemical processing, chemical processing, and oil and gas industries. Custom sizes, OEM private-label packaging and flexible MOQ are available for B2B buyers. Send your flange standard, nominal pipe size, pressure rating and quantity for a bulk quotation.

Kaxite Sealing is a China-based SS 316L graphite filler spiral wound gasket manufacturer, producing gaskets from V-shape SS 316L stainless steel tape combined with a soft graphite filler, plus inner and outer rings. SS 316L is the regular molybdenum-bearing grade, second in importance to SS 304 among the austenitic stainless steels. The molybdenum content (2–3%) gives it better overall corrosion resistance than Grade 304 — particularly higher pitting resistance and chloride crevice corrosion resistance. The low carbon content (≤0.03%) eliminates carbon precipitation during welding, so SS 316L is resistant to sensitisation and is widely used in high-gauge (over 6 mm) welded parts. Chemical composition: Cr 16–18%, Ni 10–14%, Mo 2–3%, C ≤0.03%, Mn ≤2%, Si ≤1%, P ≤0.045%, S ≤0.03%. Mechanical properties: tensile strength 485 MPa, yield strength 205 MPa, elongation 52%, density 7.9 g/cm³. This is a very common and economical spiral wound gasket. As the direct supplier and manufacturer, we can offer factory pricing on short lead times. Custom sizes, OEM private-label packaging and flexible MOQ are available for B2B buyers. Send your flange standard, nominal pipe size, pressure rating and quantity for a bulk quotation.

Kaxite Sealing is a China-based Monel 400 CGI spiral wound gasket manufacturer, producing gaskets from V-shape Alloy 400 (UNS N04400) tape combined with graphite, PTFE or vermiculite filler. Alloy 400 is a nickel-base alloy with resistance to a variety of corrosive conditions — most frequently specified in environments ranging from mildly oxidizing through neutral and in moderately reducing conditions. Its major application area is in marine environments and other non-oxidizing chloride solutions: it shows excellent performance against rapidly flowing brackish or seawater, outstanding resistance to chloride stress corrosion cracking, and good resistance to most alkalies, salts and organic substances. Mechanical properties: ultimate tensile strength 520 MPa, yield strength 240 MPa, elongation 48%, density 8.8 g/cm³, hardness 70 HRB. Chemical composition: Ni ≥63%, Cu 28–34%, Fe 2.5%, Mn ≤2%, C ≤0.3%, Si ≤0.5%, S ≤0.024%. Service from sub-zero temperatures up to 1020 °F (approximately 550 °C), with some capability in hydrochloric and sulfuric acids at moderate temperatures. Custom sizes, OEM private-label packaging and flexible MOQ are available for B2B buyers. Send your flange standard, nominal pipe size, pressure rating and filler material for a bulk quotation.

Kaxite Sealing is a China-based Vermiculite Filler 835 spiral wound gasket manufacturer, producing a critical service gasket designed for applications involving high temperatures or aggressive chemical media. The gasket is built from a spirally wound sealing element composed of a metal winding wire — SS304, SS316L, SS321 or Monel 400 — combined with a vermiculite based filler material. It can be supplied with inner and outer centering compression stop rings, or in sealing element form only. The spiral construction provides excellent sealing performance and delivers high levels of gasket resilience. Working range: fluid pressures up to 250 bar, temperatures from −240 °C to +1000 °C. The vermiculite filler is suitable for a wide range of operating conditions and can be adapted to suit almost all applications, including those where graphite filler would oxidise or where PTFE filler would not survive the temperature. Custom sizes, OEM private-label packaging and flexible MOQ are available for B2B buyers.
