KOHLER GP77005-RP Ceramic Valve (Hot) | Genuine Kohler Replacement Part

Reliable replacement valve for Kohler faucets

When a worn valve starts to show itself—drips, minor leaks, or a grabbing feel on the handle—replacing it with the GP77005-RP Ceramic Valve (Hot) offers a practical path back to confident faucet control. This is a genuine Kohler part, designed to match the engineering intent of Kohler fixtures and to preserve the faucet’s original performance traits. For homes with older Kohler two-handle setups, the replacement can restore the familiar, smooth action you remember, with the warm touch you expect from hot-water control.

The valve combines a precise 1/4-turn mechanism with a durable ceramic disc, built to resist wear and maintain consistent operation over time. The result is a dependable sensation in each turn, a more predictable response when you open the hot water, and a lower likelihood of nuisance drips that disrupt daily use. The GP77005-RP is intended for most Kohler two-handle faucets manufactured from 1990 through 2010, making it a targeted option for mid-life fixtures that still perform well when refreshed with an OE replacement.

• Authentic Kohler Genuine Part ensures authenticity, fit, and tested performance
• 1/4-turn ceramic valve delivers quick, clockwise close for precise control
• Ceramic disc design minimizes wear and extends service life
• Specifically compatible with many Kohler two-handle faucets from 1990–2010
• Replacement uses the same valve type; Ultra Glide upgrades are not available for this part

Before you install, take a moment to verify the model compatibility within the 1990–2010 two-handle range, then gather basic plumbing tools and shut off the water supply. Follow standard valve replacement steps to ensure a secure seal and reliable hot-water control. With careful handling and proper fit, you may notice sharper faucet response, steadier temperature control, and a quieter operation as the valve settles in.

• Compatibility check: matches Kohler two-handle faucets from 1990–2010
• Turn off water, relieve pressure, and use appropriate tools for a clean replacement
• Replace with the same valve type to preserve original performance
• Choosing an authentic Kohler part helps maintain warranty support and fixture reliability

Note that results can vary based on your faucet’s condition and installation accuracy. If you’re unsure about doing the replacement yourself, consider professional installation to protect your fixture’s longevity and ensure a proper seal and smooth operation.
