Garlock Model S End Seals offer a dependable, economical solution for sealing the space between casing and carrier pipes in new installations. Stocked in a wide range of sizes and made from flexible, UV-resistant rubber, these slip-on seals are easy to install and provide long-lasting protection using included stainless-steel clamps. With a fast turnaround and tool-light assembly, Model S is ideal for utility and infrastructure projects requiring reliable, field-ready performance.

Built for straightforward installations, Model S is designed to fit standard steel and IPS piping combinations without the need for customization. Its slip-on design makes installation simple, while the rugged rubber construction delivers strong sealing performance in underground and above-ground environments.

For misaligned or off-center pipe applications, choose Model W or Model C. For compact inventory and field trimming, use Model R.
