Tec-Seal™ products are pre-applied elastomeric thread sealants designed to seal fasteners and threaded components against fluid and gas leakage during and after assembly. They create a form-fitting gasket directly in the thread, eliminating the need for tape, bottled or field-applied sealants, and maintain joint integrity under vibration and thermal cycling across automotive, OEM, and industrial applications.
Tec-Seal™ compounds are applied directly to fastener threads and cured in place, forming a durable, elastic seal that prevents the passage of fluids, gases, fuels, and lubricants in both straight and tapered thread configurations. Compatible with a broad range of metallic substrates and thread geometries, Tec-Seal™ supports applications from filler plugs and pipe fittings to hydraulic connectors and sensor threads. Tec-Seal may be used on straight threaded parts to seal and bring torque/tension consistency to your assembly profile.
Tec-Seal™ formulations are available in multiple grades to match viscosity, texture, and performance requirements. Most grades are available in bulk form for automated application via cable applicator, flowcoater, or tumbling system, and in bottle form for lower-volume or field use.

Application Methods: Cable applicator, flow coater, tumbling system; bottle form available
Fluid Resistance: Resists salt, chlorine, acids, alkalis, natural gas, butane, propane, motor fluids, and chemical solvents
Flammability: Non-hazardous; non-flammable
Performance, Advantages and Benefits
Reliable Thread Sealing Across Fluid and Gas Applications: Tec-Seal™ forms an elastic, form-fitting gasket directly in the thread interface, creating a positive seal against most fluids, gases, fuels, and lubricants without requiring field-applied tape, paste, or liquid sealants.
Low Installation Torque, Multiple Reuses: Tec-Seal™'s friction-diminishing chemistry allows threaded components to assemble easily with common hand tools. Coated parts can be removed, readjusted, and reinstalled without reapplication, reducing waste and service time.
Long Shelf Life After Application: Once applied, Tec-Seal™ remains stable and unaffected by extended storage, allowing pre-coated parts to be inventoried and used on demand without loss of sealing performance.
Broad Chemical Resistance: Tec-Seal™ protects threaded connections against corrosion from salt, chlorine, acids, and alkalis, and resists degradation from natural gas, butane, propane, motor fluids, and chemical solvents.
Vibration Resistance and Thermal Stability: Tec-Seal™ remains elastic across a wide service temperature range and resists thermal shock, maintaining joint integrity in vibration-prone and thermally cycled environments.
Cost-Effective Pre-Application: Tec-Seal™ can be pre-applied to virtually any fastener configuration or quantity at licensed applicators worldwide, eliminating the cost and variability of manual sealant application at the point of assembly.
What thread types is Tec-Seal™ compatible with?
Tec-Seal™ is formulated for both straight and tapered thread configurations and is suitable for use on fasteners and components across a wide range of thread geometries and substrate materials.
Can Tec-Seal™ be reused after disassembly?
Yes. Parts coated with Tec-Seal™ can be removed, readjusted, and reassembled without reapplication in most service conditions. This makes Tec-Seal™ appropriate for applications requiring periodic maintenance access.
What fluids and gases does Tec-Seal™ resist?
Tec-Seal™ effectively resists natural gas, butane, propane, motor fluids, and chemical solvents. It also protects against corrosion from salt, chlorine, acids, and alkalis.
How is Tec-Seal™ applied?
Tec-Seal™ can be applied at Tectorius licensed applicators using automated bulk systems including cable applicators, flow coaters, and tumbling systems. Bottle form is also available for lower-volume or manual application requirements.
Is Tec-Seal™ safe to handle and ship?
Yes. Tec-Seal™ is non-hazardous and non-flammable, simplifying handling, storage, and shipping compliance across all grades.
