LUKYER 77704-0104 Plug & Cover Assembly for Sta‑Rite WC112‑148/A — Replacement Kit with O‑Rings & Waterproof Tape

The LUKYER 77704-0104 plug and cover assembly is a direct-fit replacement kit that restores a multiport valve’s seal and operation for Sta‑Rite WC112‑148/A and WC112‑147 models.

If your pool or spa multiport valve is leaking, cracked, or failing to hold pressure, replacing the plug and cover assembly is a fast, cost-effective repair that avoids swapping the entire valve. This LUKYER kit includes the primary plug and cover parts plus two O‑rings and waterproof tape so you can reseal the valve and get the filtration system running reliably again.

How does this assembly fix leaks and pressure loss?

Worn or damaged plugs and covers let water bypass internal seals, causing leaks and reduced valve performance. Installing this replacement restores the original sealing surfaces and prevents cross‑port flow that leads to inefficient filtration.

• Includes new cover and plug tailored to multiport valve geometry
• Comes with two O‑rings for reliable compression sealing
• Waterproof tape supplied for thread or joint sealing as needed
• Replaces worn components without needing full valve replacement

Is this part compatible with my Sta‑Rite valve?

The LUKYER 77704‑0104 is manufactured to fit Sta‑Rite multiple port 1‑1/2" valves specifically listed as WC112‑148/A and WC112‑147. Confirm your valve part number before ordering to ensure proper fit and function.

• Designed for Sta‑Rite WC112‑148/A and WC112‑147 multiport valves
• Cross‑checks should match the valve model stamped on your housing
• Not a universal plug—verify dimensions and model compatibility

What comes in the kit and how easy is installation?

The kit arrives ready for a straightforward swap: the plug and cover assembly plus two O‑rings and waterproof tape. Installation is typically a simple mechanical replacement that requires basic tools and routine maintenance safety steps.

• Included: 1× 77704‑0104 plug & cover, 1× 35505‑1228 spare O‑ring, 1× 35505‑1275 cover O‑ring
• Also included: waterproof tape to help seal threaded or mating surfaces
• Installation usually needs only hand tools and standard disassembly of the multiport valve
• Follow manufacturer safety: depressurize system and shut off pump before servicing

How long will this repair last and what maintenance is recommended?

Replacing degraded seals and covers restores function and can extend service life, but longevity depends on water chemistry and usage. Inspect O‑rings and plastic parts during routine seasonal maintenance and replace at the first sign of wear.

• Durability depends on pool chemistry, sunlight, and mechanical stress
• Inspect annually or when you notice pressure or flow changes
• Keep spare O‑rings on hand for quick future replacements

Who is this for: Pool technicians, DIY homeowners, and facility maintenance staff who need a precise, economical way to repair Sta‑Rite 1‑1/2" multiport valves. If you want to stop leaks, avoid buying a full valve, and restore filtration performance with a single repair kit, the LUKYER 77704‑0104 provides the matching parts and sealing components required for a dependable fix.
