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

Meet the Green Leaf Nylon 1/8 in. MPT to 3/8 in. Barb Adapter — a compact, lead-free connector engineered to bridge small pipe ports with flexible tubing. This nylon adapter converts a 1/8" male pipe thread inlet to a 3/8" barb outlet, giving you a reliable, easy-to-install solution for a variety of water and fluid transfer applications.

  • Lead-free nylon construction delivers dependable chemical resistance and durable performance over time, making it suitable for many lightweight fluid systems.
  • Inlet: 1/8 in. MPT provides a standard small-thread connection for tight spaces and modular setups.
  • Outlet: 3/8 in. barb pairs with common 3/8" tubing and can be secured with a hose clamp for a solid seal.
  • Compact, lightweight design helps you keep your projects tidy and accessible, even in cramped or portable installations.
  • Bagged packaging ensures the component arrives protected and ready for immediate use in your system.

Ideal use cases

  • Irrigation and garden setups where small-diameter connections need to feed larger tubing runs.
  • Hydroponics and home growing systems requiring a simple 1/8" MPT to 3/8" barb transition.
  • DIY fluid transfer projects, laboratory experiments, or hobbyist builds that call for a reliable nylon adapter.
  • Aquarium or wildlife-watering setups where secure hose connections are essential.

How to install

  1. Wrap the 1/8" MPT port with an appropriate thread sealant if your application requires one, then thread the adapter into place by hand and snug with an appropriate wrench—avoid over-tightening.
  2. Slide 3/8" tubing over the barb outlet and secure with a hose clamp to ensure a leak-free connection.
  3. Test the assembly under gentle flow to verify a clean seal and proper fit before putting the system into full service.

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.
