914Rubber Triangle Window Kit for Porsche 914 (1970-76)
Restore your Porsche 914’s triangle windows with the 914Rubber Triangle Window Kit, designed for all models (1970-76) and available through PMB Performance. With over 20 years of Porsche 914 expertise and a nearly two-decade partnership with 914Rubber, we’re the top retailer of their SKUs, selling more than anyone else. This kit includes precision-crafted seals and trim caps to ensure a weather-tight fit and factory-fresh appearance.
Kit Components:
- Triangle Window Seal Set (Part #914.542.325.10, 914.542.326.10): These perimeter seals are made from high-grade rubber with a larger fin than OEM, filling gaps between the guide rail and door panel for a cleaner, leak-free install. They resist UV exposure and temperatures up to 180°F, preventing cracks that lead to water intrusion—a common issue we’ve seen in our shop. Note: Early models (1970-72) with a metal tab require its removal, as it’s non-structural and can trap water, risking door rust.
- Triangle Window Trim Cap and Screws (Part #PCG.542.017.10, N.033.165.1): This set includes two reproduction trim caps with four stainless steel screws for secure installation. The caps cover the seal mounting points, providing a polished look while protecting against debris. Their corrosion-resistant design ensures longevity, even in coastal climates.
Technical Details: Compatible with all Porsche 914 model years (1970-76), this kit addresses the unique triangle window design, which vents air but is prone to seal degradation. The seals’ enhanced fin design reduces wind noise by up to 8 dB compared to worn OEM seals, based on our in-house testing. Installation requires removing the triangle window assembly; clean mating surfaces with a 50:50 isopropyl alcohol solution and secure screws to 3-4 Nm to avoid stripping. For early models, use a Dremel to remove the metal tab, then smooth the surface. Pair with 914Rubber’s Early or Late Door Window Kit (Part #914.531.905.00 or #914.531.906.00) for a complete window refresh. One kit per car.
