Compressed sheet gasket products combine fiber, binder, and filler materials into a dense sheet material. This structure allows each gasket to compress and seal uneven flange surfaces.

Common components include:

• Aramid fiber and aramid fibre for strength
• Synthetic fibers for durability
• Elastomer binder such as nitrile binder or sbr binder
• Graphite for thermal stability in select grades

This mix forms a non-asbestos sheet that replaces traditional asbestos products while maintaining performance.

Each compressed sheet provides strong torque retention. This helps the gasket maintain a seal during pressure cycles.

HTX Products designs gasket sheeting to deliver consistent seal performance. Each compressed gasket adapts to flange surfaces and fills small gaps.

Key performance features include:

• High compress strength for tight sealing
• Stable seal under heat and pressure
• Resistance to oil, water, gas, and chemicals
• Low creep and strong recovery after load cycles

Compressed sheet gasket material performs well in systems that use gas, steam, or liquid flow. The material holds its shape and supports long-term sealing.

HTX Products offers non-asbestos sheet solutions for safe and effective sealing. These gasket materials use aramid fiber and elastomer binder systems to replace asbestos.

Available material options include:

• Aramid fiber sheet for general industrial use
• Carbon and graphite blends for high heat
• Nitrile-based compressed fiber sheet for oil resistance
• Neoprene and other elastomer blends for flexible sealing

Each gasket sheet meets strict quality standards. These materials provide a balance of strength, flexibility, and chemical resistance.

HTX Products converts sheeting into custom gasket shapes with precision cutting methods. Our team produces each sheet gasket to match exact system requirements.

We support:

• Standard ASME flange gasket sizes
• Custom gasket designs from drawings or samples
• Thickness options across a wide compressed sheet range, as thin as 1/64” and can be die-cut to fit ASME B16.5 flanges or customized to any required shape and size
• Tanged and reinforced gasket configurations for added strength

Our process ensures each gasket fits correctly and creates a reliable seal at installation.

Compressed gasket material supports many industrial systems. These gasket solutions perform well in both standard and high-demand environments.

Common applications include:

• Chemical Processing: Resistant to harsh chemicals for safe, long-term operation
• Oil and Gas: Withstands the challenging conditions of high-pressure environments
• Water: Durable for various water treatment and distribution applications
• Transportation: Versatile gaskets for automotive and transportation needs
• Pulp and Paper: Reliable performance in intense processing environments
• Food and Beverage: Safe, compliant sealing solutions for regulated applications
• Nuclear Power: Designed to perform in critical, high-stakes power generation settings

Each gasket resists chemical exposure and mechanical stress. This allows the seal to remain stable during operation.

HTX Products supplies premium compressed sheet materials that use advanced binder systems. These binder materials control flexibility and sealing strength.

Binder options include:

• Nitrile binder for oil and fuel resistance
• SBR binder for water, steam, and air systems

Each elastomer binder supports proper compress behavior. This helps the gasket form a tight seal without failure.

A Ring Type Joint (RTJ) gasket is a precision-machined metallic ring used for metal-to-metal sealing applications in high-pressure, high-temperature flange connections. As torque is applied, the gasket plastically deforms to fill the flange groove, ensuring a reliable, leak-tight seal. Because of their ability to maintain integrity under extreme loads, RTJ gaskets are widely used in oil, gas, petrochemical, and industrial systems where failure is not an option.

Keep reading to learn about different types of RTJ gaskets available from HTX Products, common materials used to manufacture them, and examples of oil and gas applications that rely on them.

The R-Type is the most common RTJ gasket, available in oval and octagonal cross-sections. Because these gaskets seal by deforming under pressure, they must be made from material softer than the corresponding mating flange. The oval design is compatible with bottom radius grooves, while the octagonal shape has a higher sealing coefficient. R-Type gaskets are rated up to 10,000 psi and manufactured in accordance with ASME B16.20 and API 6A. They are a dependable choice for general refinery, chemical, and pipeline service.

RX-Type RTJs feature a pressure-energized design that enhances the seal as internal pressure increases. This makes them ideal for systems subject to vibration or fluctuating pressure. They are interchangeable with R-Type flanges and are suitable for pressures from 1000 bar. These gaskets are well-suited to high pressures, heavy weight loads and vibration in blowout preventer (BOP) stacks.

BX-Type and SBX-Type RTJs are used exclusively with 6BX flanges and 16BX hubs. Their trapezoidal geometry and pressure-balancing holes allow them to withstand extreme operating conditions up to 20,000 psi. These gaskets are commonly used in critical oilfield components, such as blowout preventers, choke and kill manifolds, and subsea wellhead systems.

The SBX profile incorporates modified angles and sealing geometry to improve load distribution and gasket compression under pressure. They also feature intersecting vent holes that facilitate seal formation underwater. Type Gaskets are made from non-corrosive material, in compliance with API 17D.

These gaskets combine a precision-machined serrated metal core with a soft facing material (i.e., expanded graphite, mica, PTFE). They create a high-integrity seal at comparatively low bolt loads and are frequently used in heat exchangers.

Featuring spherical seating surfaces, lens rings naturally self-align under compression. They are mechanically stable and resist blow-out in high temperature and high pressure applications like heat exchangers, reactor vessels, and petrochemical operations.

These gaskets feature a machined steel core with an oil-resistant nitrile coating that protects flange surfaces. They are often used for pressure testing of blowout preventers (BOPs), Christmas tree valves, and other wellhead components.
