Pinchweld top seal is a rubber edging product featuring an integrated top bulb that provides excellent sealing and edge protection. This type of pinchweld top bulb is designed to compress against surfaces to help block out dust, water, noise, and vibration while finishing and protecting exposed edges on doors, panels, hatches, and openings. It is widely used in automotive, marine, industrial, and fabrication applications where a reliable seal and durable edge finish are essential. At ACT Foam, our pinchweld top seal is available in PVC and EPDM materials to meet different performance and environmental needs.
