There are two separate stages in the life of a gasket or seal:

  • The part’s primary fit and function.
  • How well the part can endure its environment.

As a result, Qualiform’s experts consider both factors in the design stage of rubber gaskets, so they will not be the weakest link in a product. Similarly, consider the environmental factors in gasket or seal application, such as

  • Flammability – UL specifications, heat resistance
  • Function – the motion acting upon it
  • Impermeability – exposure to gases
  • Organic materials need – fungus resistance, odor, tastelessness
  • Temperature extremes – heat, cold
  • Weather exposure – water, ozone, sunlight

Whether you need large or small runs, our manufacturing capabilities mean a prompt response to your sealing needs.

Gray seal created by transfer molding process.

Static Rubber Seals

Where there is little or no motion of assembly parts on the seal.

An initial compression or intervallic compression (open and close) characterizes this type of seal:

  • A liquid seal in a hose joint
  • A door seal on a home

With the use of a Static Seal, compression pressure operates in a vertical direction relative to the face of an O-ring or face gasket and constricts two different surfaces to eliminate gaps.

Dynamic Rubber Seals

Where there is repetitive motion of assembly parts on the seal.

Repeated actions on the seal, recurrent or intermittent, characterizes this type of seal:

  • shock absorption device
  • piston ring seal

Choosing the right material is critical when it comes to rubber seals and gaskets. The performance and longevity of a seal depends on how well the material can withstand its operating environment. An expert rubber gasket supplier considers the following to ensure that each component perform as intended, not just at the start, but throughout the indicated service life:

Temperature Resistance

Materials behave differently at high and low temperature. Selecting the proper material that does not stiffen, soften and break down at a certain temperature exposure prevents premature failure of rubber seals and gaskets.

Chemical Compatibility

Rubber seals and gaskets often come in contact with oils, fuels, solvents, acids and other aggressive substance. Ensuring the material’s compatibility to the substance that it will encounter will prevent swells, cracks and degradation.

UV/Ozone Exposure

Outdoor and industrial environments expose materials to sunlight (UV) and ozone, which can cause embrittlement and cracking over time. Certain elastomers are formulated for excellent UV/ozone resistance, ensuring that outdoor-exposed seals and gaskets stay flexible and effective.

Compression Set

Low compression set indicates that a seal or gasket can maintain contact between surfaces despite repeated loads or thermal cycling, which is a key factor for leak-free performance in dynamic and fluctuating conditions.

Abrasion and Tear Strength

Applications with movement, friction and repeated assembly are prone degradation leading to leaks that may require replacement. to Rubber seals and gaskets with high abrasion and tear resistance are durable and requires less maintenance.

With Qualiform LLC, we produce a wide variety of configurations tailored to different sealing needs:

Static Seals

Static seals are designed for assemblies with little to no relative motion between parts such as door seals, hose joints and flange faces. They work by closing gaps and preventing leaks, providing a reliable, long-term seal with minimal tear.

Dynamic Seals

These seals are often applied in materials that involve repetitive motion such as rotary shafts, hydraulic pistons, piston seal rings and shock absorbers. These seals maintain containment while allowing movement.

Flange Gaskets

Ring-shaped seals installed between mating pipe, valves or equipment flanges to create a tight seal under pressure, preventing gas or fluid leaks. These are commonly seen in piping systems, fuel lines and HVAC applications.

Face Gaskets

These seals are mounted on flat surfaces of an assembly part and are designed to seal interfaces where pressure or fluid leakage could occur. These are used in automotive, HVAC, pump systems, machinery housings and mechanical enclosures.

Bonded Seals

Also known as Dowty seal, in which a molded elastomer ring is bonded to a metal washer for reliable sealing in high pressure application. The metal washer provides structural support while the rubber element creates a tight seal, making it ideal for hydraulic and pneumatic fittings.

Custom Shapes

These are tailor-made seals and gaskets molded to specific geometries and performance requirements, making them ideal for OEM equipment or extreme operating conditions, where off-the-shelf products won’t suffice.

T-shaped Rubber Gasket

Living up to its name, these have a distinctive “T” cross-section designed for edge sealing, panel gaps and door perimeters, making them highly effective for weather stripping applications.

Flat Round Rubber Gasket

These are classic circular, flat-profile seals typically cut from sheet material or molded, available in multiple thicknesses and diameters to suit various applications. They are commonly used for pipe flanges, covers, lids, housings, hydraulic flanges, drains, and other general fluid sealing surfaces.

Circular Rubber Gasket

Precision-molded ring-shaped seals with consistent cross-sections designed to seal around circular openings in pressure fittings, valves, bulkhead seals, and flange connections. Common forms include O-rings and flat washer-style gaskets, widely used in pipe fittings and other round sealing applications.

Selecting the right manufacturing method is crucial for quality, precision, cost, and performance. The most common processes used by rubber gasket suppliers like Qualiform LLC include:

Compression Molding

In this process, the rubber is placed in an open mold and heated under pressure, causing it to cure into the mold’s shape, making this method ideal for simple, larger parts and cost-sensitive small to medium production runs. It offers lower tooling costs and works with many elastomers, commonly used for basic gaskets, large seals, and industrial components.

Transfer Molding

Transfer molding is a process in which a preheated rubber is forced through a sprue into a closed mold, curing into intricate shapes with tighter tolerances than compression molding. This method provides better surface finish and consistency, making it ideal for mid‑complex gaskets and bonded assemblies with inserts.

Injection Molding

Liquid rubber is injected under high pressure into a closed mold, curing into complex shapes with high precision and repeatability. This process is ideal for medium to high‑volume production of intricate seals and tight‑tolerance gaskets, offering fast cycles and minimal scrap despite higher tooling costs.

Rubber-to-Metal Molding

Rubber is molded or vulcanized directly onto metal or plastic parts, combining elastic sealing with rigid support for bonded seals, grommets, and assemblies. This process, using injection or transfer molding, ensures durable attachment for components like vibration‑damping mounts, precision seals, rollers, and bumpers.

Every sealing application has unique demands. Below is a guide to common elastomer materials and their strengths:

  • EPDM Rubber – Excellent weather, ozone, and heat resistance; ideal for outdoor and water sealing applications.
  • Nitrile Rubber – Strong resistance to oils, fuels, and hydraulic fluids; widely used for automotive and industrial sealing.
  • FKM/Viton Rubber – Premium heat and chemical resistance; perfect for high-temperature and aggressive chemical environments.
  • Silicone – Exceptional temperature range and flexibility; great for food, medical, and high-heat applications.
  • Neoprene Rubber – Balanced performance with good weather and chemical resistance; often used in refrigeration and general sealing.
  • Butyl Rubber – Low gas permeability and excellent damping; common in pharmaceutical, air-bladder, and insulation seals.
  • Natural Rubber – High abrasion resistance and elasticity; suited for dynamic seals with minimal chemical exposure.
  • Rigid and Flexible – For structural or cushioning applications
  • Thermoplastic Elastomers (TPE) – Combines rubber-like flexibility with plastic processing benefits.
  • Synthetic Rubbers – Engineered for specific chemical, temperature, or mechanical requirements.
