Restore Watertight Integrity to New Standard Portlights
The Lewmar New Standard Portlight Seal Kit is a genuine OEM replacement designed to renew the watertight performance of New Standard portlights. As seals age and compress, leaks and drafts can develop, this kit restores a tight, reliable seal to keep your cabin dry and protected.
Durable, Marine-Grade Sealing Material
The gasket is made from high-quality, UV-resistant marine polymer engineered to withstand sunlight, saltwater exposure, and temperature fluctuations. This ensures the seal maintains flexibility and compression strength over years of use.
Precision-Cut for the New Standard Portlight Profile
Each seal kit is shaped specifically for Lewmar New Standard portlights (1997 onward), guaranteeing a perfect fit within the frame channel. This precise geometry ensures the acrylic closes smoothly and compresses the seal evenly for maximum leak protection.
Improves Comfort & Reduces Noise
A fresh seal eliminates rattling, stops air leaks, and reduces wind noise, especially important on forward or windward side portlights. It also protects interior linings and equipment from moisture damage.
Available for Multiple New Standard Sizes
Lewmar produces seal kits across the full New Standard portlight range, including both fixed and opening models. This ensures owners can match the correct kit to their exact portlight size for fast, accurate maintenance.
