In-Store Exclusive

This one's worth the trip to the store.

Brands like Weber, Milwaukee, Yeti, and DeWalt restrict where their products can be sold online — and for good reason. In-store buyers get authentic products, full manufacturer warranty, and access to pricing that simply isn't allowed to be advertised on the web.

  • Authorized dealer network · Full manufacturer warranty & support
  • Guaranteed authentic · No counterfeits, no gray-market resellers
  • The brands set these standards · Be wary of sellers who don't follow them

Every order helps keep your local hardware store on the corner.

Why we built NHG
You might find it for less locally. Independent retailers often offer competitive pricing — some products are even cheaper in-store than online.
Real expert advice — not search results. Independent hardware staff know their inventory and the local conditions you're working in.
Keep the neighborhood working. Every dollar spent at an independent retailer returns roughly 3x more to your local economy than at a national chain.

About Product Overview

Upgrade your evaporative cooling setup with the Dial 20 in. Evaporative Cooler Water Hook-Up Kit. Crafted in durable black plastic, this long, slim line is designed to connect your water supply cleanly and securely to any residential evaporative cooler.

Key features

  • Length: 20 inches for flexible routing around cabinets, in attics, or utility spaces
  • Profile: slim 1/8-inch width for tidy, unobtrusive installation
  • End connections: two 3/8-inch diameter ends for standard water fittings
  • Material: rugged black plastic built to endure regular use and moisture exposure
  • Compatibility: designed for all residential evaporative coolers
  • Packaging: bagged for clean handling and storage

Why this kit matters

Replacing a worn or inflexible water line is essential to maintain steady cooling performance. The Dial water hook-up kit provides a secure, crew-friendly connection with ample length to minimize strain on fittings and hoses. The uniform 3/8-inch ends simplify installation with standard supply lines, so you can upgrade without hunting for adapters or custom parts. The black plastic construction offers a durable, weather-tolerant solution suitable for indoor utility rooms or outdoor installations where moisture is a factor.

Ideal use cases

  • Replacing aging or cracked hoses on existing residential evaporative coolers
  • Installing or retrofitting a cooler in utility rooms, garages, or attics where space requires a longer run
  • Routine maintenance you perform during seasonal cooling cycles to prevent leaks and maintain efficient operation
  • Property management or rental units needing a reliable, universal hook-up option that fits multiple cooler models

How to use

  1. Power down the cooler and shut off the water supply to prevent leaks during installation.
  2. Remove the old connection from both ends, if applicable.
  3. Attach each 3/8-inch end of the 20-inch hook-up kit to the corresponding water fittings on the cooler and supply line.
  4. Secure connections, check for leaks, and restore power to the cooler to test performance.

Elevate your cooling reliability with a purpose-built Dial water hook-up kit that’s ready to handle the demands of residential evaporative systems. Add it to your cart today and enjoy a cleaner, more dependable water connection for your cooler.

Their Counter
Try local first · we'll wait

The stores we send you to are local and independently run — often for generations, the kind of place where someone behind the counter knows the regulars. We don't own them. We just think they deserve the foot traffic. They can put most of what we sell on their next truck. Ask there before you check out here.

About our directory. National Hardware Group is an independent retailer and directory. The local stores we list and link to are separately owned and operated — we have no ownership stake in any of them, and most pay us nothing to be included. That includes plenty of stores flying a co-op banner that people don't realize are locally owned and run, not operated by a corporation. Store owners can choose to upgrade their listing for an enhanced presence or pickup features, but the base directory is free, and inclusion is never a paid endorsement.
