Valterra Bladex 3" Waste Valve Seals (Black) — Pair with Mounting Hardware, OEM Fit

If your RV, marine system or plumbing fixture uses a Bladex rotating waste valve and you notice seepage, binding, or uneven movement, replacing the worn seals with purpose-made Bladex seals restores proper fit and function. These 3" seals come from Valterra as the specified replacement for the Bladex valve line and are supplied in a two-seal pack complete with the necessary mounting hardware.

How do these seals prevent leaks and sticking?

The seals are molded to match the original Bladex valve geometry so they maintain a tight contact surface as the valve turns. That correct fit keeps liquid from bypassing the gate and reduces the chance of the pinching or catching that causes rough rotation.

• Precision-molded profile matches Bladex valve cavities
• Durable elastomer resists compression set and deformation
• Includes hardware to ensure correct installation and alignment

Will these fit my existing 3" Bladex waste valve assembly?

Yes — these T1003-9VP seals are sized specifically for 3" Bladex rotating waste valves. They are intended as the recommended replacement seals for the Bladex product line, designed to drop into the original valve housing without modification.

• Marked for a 3" valve bore to match factory dimensions
• Pack includes two seals so both mating surfaces can be replaced together
• Hardware supplied for a straightforward swap-in installation

What materials and durability can I expect?

Manufactured from a resilient elastomer, these seals resist the common causes of seal failure like flattening and edge distortion. That durability translates to longer periods between replacements and more consistent valve action under normal use conditions.

• Engineered elastomer resists wear and maintains compression resistance
• Black finish for standard OEM appearance and UV/chemical tolerance
• Designed to minimize gate pinching and misalignment over repeated cycles

How easy is installation and what’s included?

Installation is straightforward for anyone familiar with basic waste valve service: remove the old seals, clean the valve cavity, and press the new seals into place using the included hardware to secure alignment. The kit provides both seals plus the hardware pieces needed to restore factory-style operation.

• Pack of two replacement seals to refresh both sealing surfaces
• Included mounting hardware for correct positioning and retention
• Simple service steps—no special tools required for most installs

Who is this for: This Valterra T1003-9VP kit is aimed at RV owners, boaters, fleet maintainers, and plumbing technicians who service Bladex rotating waste valves and need a direct-fit, manufacturer-recommended replacement. Choose it when you want a like-for-like repair that reduces leaks, prevents gate pinching, and restores smooth valve rotation without complicated modifications.
