Gasket & Sealing Material Categories In Stock

Gulf Union Ozone stocks all principal gasket types for ASME and API pressure flange applications in Saudi Arabia oil and gas, petrochemical, and utility services.

Type 01

Ring Type Joint (RTJ) Gaskets

Oval and octagonal RTJ gaskets to ASME B16.20 for ASME B16.5 Class 600 through 2500 flanges and API 6A wellhead equipment. Materials: soft iron ASTM A108 Grade 1018 (Brinell ≤ 90 HB), low-carbon steel F5 (≤ 137 HB), SS 304 (≤ 160 HB), SS 316L (≤ 160 HB), and Inconel 625 for sour or extreme high-pressure service. Ring numbers R-11 through R-105 (octagonal) and RX/BX gaskets for API 6A 10,000 PSI and 15,000 PSI wellhead connections. Supplied with MTC and dimensional reports per ASME B16.20.

Type 02

Spiral Wound Gaskets

Spiral wound gaskets to ASME B16.20 for ASME B16.5 Class 150 through 2500 raised face (RF) and flat face (FF) flanges. Winding strip: SS 304, SS 316L, Alloy 825, or Hastelloy C-276. Filler: flexible graphite (most common), PTFE, or mica for high-temperature service. Centering ring: carbon steel (zinc phosphated) or SS 304/316. Inner ring (SS 316L) for Class 600 and above as required by ASME B16.20. NACE MR0175 compliant for sour gas service. Pressure classes 150, 300, 600, 900, 1500, 2500. Supplied per ASME B16.20 with full MTC documentation.

Type 03

Kammprofile (Grooved Metal) Gaskets

Kammprofile gaskets with concentric grooved metal core (SS 316L) and flexible graphite or PTFE sealing layer on both faces. For ASME B16.5 Class 150 to 2500 flanges where semi-metallic sealing with high load recovery is required — heat exchangers, pressure vessels, and critical high-pressure services. Core thicknesses 3 mm and 4.5 mm; graphite layer 0.5 mm each face. Also available with integral centering guide ring for tube sheet and heat exchanger applications. Temperature range -200°C to 550°C depending on layer material.

Type 04

Sheet Gaskets — CNAF & Graphite

Compressed non-asbestos fibre (CNAF) sheet gaskets in Flexitallic Sigma 500 (aramid fibre/NBR binder) and Garlock Blue-Gard 3000 equivalents — suitable for water, steam, oils, and mild chemicals to 260°C and 100 bar. Flexible graphite sheet (GRAFOIL equivalent, reinforced with SS 316 tanged insert) for high-temperature steam, acid, and hydrocarbon service to 550°C. Sheet stock 0.8 mm, 1.5 mm, 3.0 mm, 4.5 mm in sizes up to 1500 × 1500 mm for field cutting. Full-face (FF) and raised-face (RF) rings cut to ASME B16.21 dimensions.

Type 05

PTFE & Envelope Gaskets

Full-PTFE flat gaskets and PTFE envelope gaskets (PTFE skin over CNAF core) for corrosive chemical, pharmaceutical, and food-grade flange connections in Saudi Arabia. Virgin PTFE sheet gaskets for concentrated acids and alkalis — hydrofluoric acid, chlorine, and aggressive solvents where other materials fail. PTFE envelope gaskets (ASME B16.21) with non-asbestos insert for raised face flanges in chemical plant and water treatment systems. Dimensions ASME B16.21 Class 150 to 300. FDA-compliant PTFE for food and pharmaceutical service.

Type 06

Heat Exchanger & Expansion Joint Gaskets

TEMA-standard sheet gaskets for shell-and-tube heat exchangers (OD-cut ring for shell flange, full-face for tube-side channel), in CNAF, graphite, and PTFE. Elastomeric expansion joint sealing rings in EPDM (water, steam to 150°C), Neoprene (oil-resistant), and Viton (chemical and hydrocarbon service). Jacketed metallic gaskets with corrugated SS core and graphite or PTFE jacket for heat exchanger floating head and fixed tube sheet sealing. High-temperature boiler handhole and manhole gaskets in spiral wound and solid metal designs.
