Basic spiral wound gasket without inner ring, for standard flanges where centering is provided by the bolt circle. Suitable for ASME Class 150 to 600 raised face flanges.

Spiral wound gasket with inner ring for flange bore protection and prevention of inward buckling. Standard for Class 900 and higher, heat exchangers, and high-pressure steam flanges.

Full-configuration spiral wound gasket with both outer centering ring and inner ring. Provides maximum sealing integrity, blow-out resistance, and ease of installation. Most widely specified for refinery and offshore use.

Solid metallic oval cross-section ring gasket for API ring-type joint flanges. Line contact sealing on groove faces. Suitable for Class 600 to 1500 pressure ratings.

Octagonal cross-section ring gasket providing 95% more seating stress than oval type at the same bolt load. The standard choice for Class 900 and above high-pressure wellhead and pipeline connections.

Pressure-energised ring joint gaskets for subsea, wellhead, and critical high-pressure applications. Self-sealing under pressure — higher the pressure, tighter the seal. BX type for API 6BX flanges.

Metallic jacket filled with soft material (graphite, PTFE, or asbestos-free fibre). Ideal for heat exchanger covers, large bore flanges, and applications where compressed soft materials would over-compress under high bolt load.

Metallic gasket with corrugated profile for use in heat exchangers and pressure vessels. The corrugations provide controlled seating stress distribution across large-diameter flanges. Available plain or with soft material coating.

Unmodified PTFE gaskets for maximum chemical resistance. FDA-compliant grades available for pharmaceutical and food processing. Virtually universal chemical resistance including hydrofluoric acid, fuming acids, and strong alkalis.

Biaxially expanded PTFE gaskets with superior creep resistance compared to standard PTFE. Lower required bolt load enables sealing on light-duty flanges and glass-lined vessels. Excellent conformability to imperfect flange surfaces.

PTFE reinforced with glass fibre for improved mechanical strength and creep resistance. Suitable for applications requiring higher compressive strength than virgin PTFE without sacrificing chemical resistance significantly.

Pure exfoliated graphite gaskets for extreme temperature service. Highest temperature rating of any non-metallic gasket. Suitable for steam boilers, furnace flanges, reactor nozzles, and refinery process lines.

Flexible graphite gasket with 316 stainless steel tang insert for blow-out protection. Mandatory for high-pressure steam flanges and refinery process flanges where unrestrained graphite gaskets are prohibited.

Compressed non-asbestos fibre gasket optimised for saturated and superheated steam service. Aramid fibre with EPDM binder — approved for steam at pressures up to PN 40. Widely used in process plant steam distribution.

CNAF gasket formulated for hydrocarbon service — mineral oils, lubricants, fuels, and natural gas at moderate temperatures and pressures. NBR binder provides excellent oil and fuel resistance.

EPDM rubber gaskets for hot water, steam (low pressure), HVAC systems, and outdoor weathering service. Excellent resistance to UV, ozone, and weathering. Standard for flanged water piping and cooling systems.

Nitrile rubber gaskets with excellent resistance to mineral oils, fuels, hydraulic fluids, and petroleum-based products. Standard for fuel oil lines, hydraulic systems, and lubrication flanges.

Neoprene (chloroprene rubber) gaskets for moderate oil resistance combined with excellent ozone, UV, and weathering resistance. Used in refrigerant piping, marine applications, and outdoor industrial installations.

White virgin PTFE sheet for cutting standard and custom gaskets in-house. Supplied in skived and moulded forms. Consistent density and thickness tolerance for reliable gasket performance.

Biaxially expanded PTFE sheet for low-bolt-load applications and conformable sealing. Available in sheet form and as continuous rolls of ePTFE sealing tape for on-site flange sealing.

PTFE sheet with 15% or 25% glass fibre reinforcement for improved rigidity and creep resistance. Beige/grey colour. Suitable for applications requiring higher compressive strength than virgin PTFE.

Pure exfoliated graphite sheet for cutting high-temperature gaskets. Available in plain (bare) form and SS 316 tang-reinforced form for blow-out resistance in high-pressure steam service.

General purpose compressed non-asbestos fibre sheet for cutting flanged joint gaskets. Suitable for water, steam, oils, air, and mild chemicals. Most economical CNAF grade for routine maintenance use.

High-temperature CNAF sheet for steam service up to 400°C and 100 bar. Aramid fibre with EPDM binder. Approved for use in boiler-house and steam distribution flanges.

EPDM rubber sheet for water, steam, HVAC, and outdoor service. Available in multiple hardness grades. Supplied in roll or flat sheet form. SWR Certification on request.

Nitrile rubber sheet for oil, fuel, and hydraulic fluid resistant gasket fabrication. Available in smooth and fabric-inserted grades for different mechanical requirements.

Precision cutting of gaskets to any customer-supplied drawing or dimensional specification. CNC water-jet cutting, die cutting, and lathe machining for metallic profiles. Minimum order: 1 piece. Turnaround: 24–72 hours depending on complexity.

High-volume gasket production for EPC contractors, OEM manufacturers, and stocking distributors. We handle 500 to 50,000 piece orders with consistent tolerances and competitive pricing at all volumes. Annual rate contracts available.

Priority production for plant emergency shutdowns, maintenance turnarounds, and pipeline repairs. Call xxxxxxxxx to activate emergency order processing. We confirm stock availability and production feasibility within 1 hour.

Free material selection and specification review for new projects and problem-solving on repeat gasket failures. Our engineers review your operating conditions — temperature, pressure, process fluid, flange specification — and recommend the optimum gasket type and material.

Material Test Certificate issued and signed by PrecisionSeal Industries's authorised quality representative. Includes material identification, chemical composition, mechanical properties, dimensional confirmation, and heat number traceability. Required for most industrial and oil & gas supply chains.

Material Test Certificate co-signed by an independent third-party inspection authority (Bureau Veritas, SGS, Lloyd's Register, TÜV Rheinland, or TOYO). Required for offshore equipment, nuclear piping, high-pressure vessels, and projects with Class 1/Class 2 documentation requirements.

Full TPI facilitation at our India manufacturing facility. Inspection scope includes raw material traceability, dimensional inspection, hardness testing, hydrostatic testing, and visual examination. Inspection notification issued 48 hours in advance.

Detailed dimensional inspection reports for precision-machined gaskets (ring joint, metal jacketed, corrugated metallic). Reports include measured values against drawing tolerances for all critical dimensions with inspector's signature.

PrecisionSeal Industries holds API 6A monogram certification from the American Petroleum Institute. This covers the manufacture of sealing ring gaskets and related components used in wellhead and Christmas tree equipment. API 6A certificate available for client review on request.
