Plumb Pak Flapper Tank Ball

The Plumb Pak Flapper Tank Ball delivers universal compatibility across plastic, brass, and old-style Crane flush valves — solving the inventory headache that plagues service plumbers. The vinyl construction handles Montana’s hard water better than rubber alternatives, and the PP23503 model adds chemical resistance for tanks dosed with blue tablets.

Universal Valve Compatibility That Actually Works

Plumb Pak engineered these flappers to work with plastic, brass, and old-style Crane flush valves. That covers 90% of residential toilets without guessing games. The product line includes three distinct models: PP23503 for chemical resistance, PP835-3 as the standard workhorse, and PP23592 specifically for Kohler 1.6 GPF toilets.

The standard PP835-3 measures 4-3/8 inches long by 1-7/8 inches wide — dimensions that fit most American toilet tanks built since the 1960s. Contractors report success with various flush valve materials including plastic, brass, and old-style crane valves.

Model Number	Application	Material	Key Feature
PP23503	Universal	Chemical-resistant vinyl	Resists toilet bowl cleaners
PP835-3	Universal	Standard vinyl	Basic replacement
PP23592	Kohler 1.6 GPF	Rubber	Kohler-specific fit

Chemical Resistance and Montana Water Conditions

Montana municipalities deal with mineral-heavy water that eats standard rubber flappers. The PP23503’s chemical-resistant vinyl construction stands up to both hard water deposits and those blue cleaning tablets homeowners love. Made from durable vinyl, it ensures a secure seal and longevity.

The integral chain and trunnion come pre-attached — no hunting for the right chain length or fighting with corroded metal parts during a service call. The integral trunnion and chain connect to flush lever and valve without additional hardware.

Installation Without the Hassles

These flappers include integral chain and trunnion, eliminating the most common installation headaches. The hook attachment system clips securely to the flush valve ears. No tools needed.

The black finish hides mineral buildup better than clear or colored alternatives — maintaining a cleaner appearance in hard water areas.
