Industrial C210 Porthole Seal 12 x 1220mm For Marine Vessel Window

Sermia's C210 Porthole Seal, 12 x 1220 mm, is a replacement seal designed for marine vessel porthole windows, providing a dedicated gasket interface between the porthole frame and glazing to support proper fit and sealing. The item is listed as brand Sermia, model C210, with MPN C210, and the current listing from VB Industrial Supply describes it as New – Open box, indicating a new condition part that may have been removed from packaging or surplus stock. The 12 x 1220 mm size shown in the product title denotes the seal's overall length and cross‑section dimension as typically referenced for Sermia C210 assemblies, assisting buyers in confirming compatibility with their existing porthole hardware and installation envelopes. This seal is intended for use with porthole window installations on ships or boats and is part of routine vessel maintenance or repair to restore or maintain the expected sealing performance of viewing ports under typical marine exposure.
