The Rusco 1.5" O-Ring Gasket Kit is a complete replacement seal kit specifically designed for Rusco 1-1/2" spin-down sediment trapper filter housings. The kit includes the necessary O-rings and gaskets required to properly reseal your Rusco 1.5" sediment filter housing, helping prevent leaks and restore a watertight seal between the housing body, cap, and flush valve assembly.

This kit is engineered exclusively for Rusco 1.5" (1-1/2") spin-down sediment trapper models, including the Rusco 1-1/2" polyester and stainless steel mesh filter housings. It is not compatible with Rusco 1" or 2" housings — be sure to verify you own a 1.5" model before ordering. Using the correct size kit ensures a proper fit and long-lasting leak-free performance.

We recommend inspecting and replacing the O-rings and gaskets on your Rusco 1.5" sediment filter housing at least once a year, or anytime you notice leaking, cracking, or hardening of the seals. If you frequently flush the housing or service the screen, replacing the seals more often helps maintain a reliable seal and prevents premature housing wear.

No special tools are required to install this Rusco O-Ring Gasket Kit. Simply shut off the water supply, depressurize the system, unscrew the housing cap, remove the old O-rings and gaskets, clean the grooves, and install the new seals. Lightly lubricating the new O-rings with a silicone-based, food-grade lubricant before reassembly helps ensure a proper seal and extends the life of the kit.

Yes. The Rusco 1.5" O-Ring Gasket Kit is manufactured with materials suitable for use in potable water systems, consistent with Rusco's spin-down sediment trapper product line used in residential, commercial, irrigation, and well-water applications. For specific NSF/ANSI certification details, refer to the manufacturer's documentation, as certifications apply to the complete Rusco filter system rather than the individual replacement seal kit.
