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

The B&K 1/2 in. MPT X 1/2 in. D MPT Polyethylene 6 in. Sprinkler Cut-Off Riser is the clean, dependable solution for isolating a sprinkler zone during maintenance or repairs. At 6 inches long, it provides a convenient, accessible shut-off point without disturbing surrounding soil or buried line work.

Built from durable polyethylene, this cut-off riser resists corrosion and chemical exposure common in irrigation environments. With an 80 psi maximum pressure rating and a 140°F maximum temperature, it handles typical residential and light commercial sprinkler systems with ease, delivering reliable performance year after year.

  • 1/2" MPT to 1/2" MPT connections match standard irrigation fittings, enabling quick, hassle-free integration into existing lines.
  • 6-inch length offers easy access for service tools and hands-on maintenance without needing extensive digging.
  • Polyethylene construction delivers a lightweight, durable alternative to metal risers, reducing corrosion risk and easing installation.
  • Practical performance specs: up to 80 psi and up to 140°F, covering the demands of most home irrigation setups.
  • Certification notes: IAPMO certified – No; NSF listed – No. Suitable for standard irrigation tasks where strict certification isn't required.

Ideal uses and scenarios

  • Zone isolation during routine maintenance or seasonal service without draining the entire system.
  • Temporary access point for sprinkler head replacement, valve service, or line repairs.
  • Simple upgrade or repair in networks that use 1/2" pipe threads, keeping project timelines tight and costs low.

Installation tips

  • Ensure all threads are clean and dry before assembly. Use an appropriate thread sealant or PTFE tape rated for water connections to prevent leaks.
  • Hand-tighten first, then snug with a wrench to avoid over-tightening and potential damage to the polyethylene body.
  • Pressurize the line gradually and inspect for leaks around the threaded connections; re-tighten if necessary.
  • Store in a cool, dry place when not in use and shield from prolonged direct sunlight to maximize the life of the polyethylene component.

Choose the B&K 1/2 in. MPT X 1/2 in. D MPT Polyethylene 6 in. Sprinkler Cut-Off Riser for a lightweight, reliable, easy-to-install shut-off point that helps you manage sprinkler zones with confidence.

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.
