Trelleborg Debuts Tran-SECURE Elastomer Manway Nozzle Gaskets

FORT WAYNE, Indiana - October 2024 - Trelleborg Sealing Solutions has debuted its Tran-SECURE elastomer manway nozzle gaskets for chemical transportation customers.

These high-grade elastomer gaskets are specially designed with superior sealing capabilities and simplified manufacturing processes, providing exceptional performance for appropriately torqued tank car manways transporting the most aggressive chemicals.

The manway nozzle gaskets are made from high-grade fluoroelastomer (FKM) materials offering enhanced chemical resistance, robust mechanical strength and a wide temperature range. Their single-piece design with a chevron profile ensures excellent sealing and simplified manufacturing. Leveraging material science and fully integrated engineering, they are developed with advanced materials and in-house manufacturing, helping to prevent non-accident releases (NARs). Produced in ISO 9001 and ISO 14001 certified facilities, they ensure consistent quality and full traceability from formulation to final product.

The chemical industry faces many challenges both in the processing of materials and in the transportation of these materials to customers. According to the Association of American Railroads, the manway is the leading cause of NARs, meaning it is critical that the industry has a readily available and reliable source for high-quality gaskets.

Thijs Menzel, global segment director, Chemical & Processing, said: “For decades, shippers, tank car manufacturers and railcar repair shops have relied on Trelleborg to provide high-performance seals and repair kits, material testing and root cause analysis support. To fulfill their need for a single-source supplier for all their sealing requirements, we developed the new Tran-SECURE elastomer manway nozzle gaskets. Our engineers designed these gaskets to stand up against aggressive chemicals and exhibit exceptional durability and longevity for transporting a broad range of chemicals and other liquid commodities.”  

The elastomer nozzle gasket is part of a broader portfolio of products for chemical transportation. Trelleborg’s Turcon Tran-SECURE polytetrafluoroethylene (PTFE) manway lid gasket is a thin, compressed gasket placed between the nozzle and manway cover designed to seal the entry and loading point into the tank car under a sufficient level of surface pressure. The portfolio also includes Tran-SECURE flat gaskets in a wide range of standard and custom materials.

Additional features and benefits of the elastomer manway lid and nozzle gaskets include:

• Turcon glass-reinforced PTFE delivering improved compressive and tensile strength while minimizing creep relaxation to ensure a tight seal over an extended period

• Turcon PTFE material enables use without retraining

• Lid gasket featuring “J” style design in FKM provides enhanced chemical resistance, robust mechanical strength and a leak-tight seal

• Cost-effective sealing solution

• In-stock for shipment within 24 hours

• Made in the USA
