Garlock Model W End Seals offer a custom, wrap-around solution for sealing the space between casing and carrier pipes in both retrofit and new installations. Built to exact customer dimensions, they accommodate off-center carrier pipes and simplify alignment challenges while delivering a secure, long-lasting seal. With durable, weather-resistant materials and a self-curing peel-and-stick seam, they install quickly with minimal tools, making them ideal for tight job sites and retrofit work.

Designed for versatility, Model W seals are engineered to perform in harsh environments, resisting water, UV exposure, and chemical intrusion. The flexible wrap design conforms easily around existing pipes, while stainless steel clamps at both ends ensure reliable sealing performance.

For UV resistance, select Model W with EPDM material. Select buna/nitrile material for oil and gas applications, and neoprene for wastewater applications.

If a custom, wrap-around solution isn’t a requirement for your application, select Model S or C for a standard pull-on option in new installations, and select Model C for custom sizes.
