♦      Euro based Train OEM                                                             Locomotive Engine compartment seal                  Off the shelf

This EU based project required a bulb seal profile that was compliant with all the key regulations for Flame, Smoke, and Toxicity and met US sourcing requirements.

The Seal-Fast™ rubber blend was developed to be compliant with NFPA130 fire standards and met the “local USA content” contract requirements.


♦      North American based Train OEM                                         Coach door and window seals                               Off the shelf

The client required NFPA130 compliant material, USA content and a continuous loop design to prevent leakage.

We provided a fitted continuous loop vulcanized seal made from our special D3-228-S044 material which met their design, USA content and performance requirements.


♦      Multi National Train OEM                                                          Power Supply door panel seal                              Custom

The client’s Euro customer design center won a USA train project.  It required a custom seal for the power supply enclosure which had unique design characteristics and was FST compliant with US sourcing.

The custom seal lengthened the wing flange and optimized the CLD characteristics of the wide radius mounting edge.  Made with FST/NFPA130 complaint flame retardant rubber, it also met the US sourcing requirements.
