Danco makes plumbing repair parts. They’re one of the largest plumbing repair, replacement, and remodel suppliers in the home improvement industry, but around here they’re known for one thing: toilet parts that solve real problems.
Tank-to-Bowl Gaskets and Universal Flappers
Their tank-to-bowl gaskets get the engineering right. The bolts are 5/16” x 3-1/4” galvanized steel — proper dimensions for both standard and elongated toilets. The gasket itself uses a U-shaped design that’s thicker and more flexible than standard flat gaskets. This matters when you’re dealing with Montana’s temperature swings that can warp and crack cheaper gaskets.
The kit fits both 2-inch and 3-inch flush-valve openings, which covers nearly every toilet you’ll encounter. The double-nut design keeps the bolts from loosening over time — a simple feature that prevents callbacks.
| Tank-to-Bowl Gasket Specifications | Value |
|---|---|
| Bolt Size | 5/16” x 3-1/4” |
| Material | Galvanized steel bolts |
| Gasket Design | U-shaped (thicker/more flexible) |
| Compatibility | 2” and 3” flush valves |
| Fastening | Double-nut design |
Their universal toilet flappers solve the most common toilet problem: phantom flushes from worn seals. Made from durable natural rubber that resists warping, these flappers maintain their shape longer than the cheap vinyl alternatives. The chemical-resistant rubber prevents premature breakdown from toilet bowl cleaners — a common failure point.
The design fits standard 2-inch flush valves and provides a positive seal to stop leaks. No special tools, no complicated installation. Tool-free installation with a metal pull chain included.
HydroRight Dual Flush Systems and Washer Assortments
Danco’s HydroRight dual flush converter turns water-wasting old toilets into efficient dual-flush units. The specs tell the story: converts to 1.28, 1.6, or 3.5 GPF options with 358-degree handle rotation and 205-degree arm adjustment. Those adjustment ranges mean it’ll work with nearly any tank configuration.
The best part? Drop-in design requires no tank removal. You’re looking at a 20-minute conversion versus hours of wrestling a tank off and back on.
| HydroRight Specifications | Value |
|---|---|
| Flush Options | 1.28/1.6/3.5 GPF |
| Handle Rotation | 358 degrees |
| Arm Adjustment | 205 degrees |
| Installation | Drop-in (no tank removal) |
Their beveled washer assortments cover the faucet repair basics with sizes from 00 (1/2”) through 3/8L. The neoprene rubber construction handles high temperatures — critical for hot water applications where standard rubber fails. The tapered design creates a more secure shut-off than flat washers, especially in older faucets with worn seats.
| Beveled Washer Specifications | Value |
|---|---|
| Sizes Included | 00 (1/2”), 0, 1/4, 1/4L, 3/8, 3/8L |
| Material | Neoprene rubber |
| Temperature Rating | High temperature resistant |
| Design | Tapered (beveled) for positive shut-off |
Contractors note their universal fit for Kohler and American Standard models, though as budget-friendly aftermarket parts, they may not offer the same durability as OEM parts. Fair trade-off for parts that cost a fraction of manufacturer replacements.
