Tec-Seal™ is a durable, resilient sealant product line for fasteners and components with straight or tapered threads. Tec-Seal thread sealants form an elastic, form-fitting gasket directly in the threads that prevents the passage of most fluids and helps keep joints tight, even under severe vibration.

As with all other Tectorius pre-applied products, Tec-Seal can be applied directly onto your parts and fasteners at any of our licensed applicators around the globe. Tec-Seal products are available in a variety of grades. Most Tec-Seal thread sealants are available in bulk for automated application and also in bottle form for lower volume jobs.
