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 Apache Steel 1/4 in. MPT to 3/8 in. FPT Swivel Hydraulic Adapter—engineered to endure tough shop and field conditions while delivering a reliable, leak-resistant connection in your hydraulic circuits.

Designed to bridge an inlet of 1/4 in. male pipe thread (MPT) to a 3/8 in. female pipe thread swivel (FPT), this adapter lets you efficiently convert line sizes and directions without reworking your entire hose layout. The solid steel body stands up to impact, vibration, and routine wear in industrial environments.

  • Inlet: 1/4 in. MPT
  • Outlet: 3/8 in. FPT Swivel
  • Material: Steel
  • Package: 1 piece
  • Packaging: Clamshell
  • Compatibility: Connects hydraulic hoses to control valves and cylinders

Why this adapter stands out

The swivel outlet lets you angle the hose without twisting or stressing fittings, reducing installation time and mitigating leaks in tight or awkward spaces. The steel construction delivers lasting durability for demanding hydraulic systems, from farm equipment to shop presses.

Typical use cases

  • Bridge mismatched thread sizes between hoses and control valves in hydraulic circuits
  • Field repairs where space is limited and precise alignment matters
  • Retrofits and maintenance on hydraulic-powered equipment such as cylinders and actuators

Installation tips for a clean, leak-free connection

Apply an appropriate thread sealant or PTFE tape rated for hydraulic systems. Thread the adapter onto the inlet by hand, then snug with a wrench to the recommended torque. After pressurizing the system, inspect for leaks and avoid over-tightening that could damage threads.

Who is it for?

Ideal for hydraulic technicians, maintenance professionals, and DIY enthusiasts performing upgrades or repairs on hydraulic hoses, control valves, and cylinders. The compact 1/4 in. to 3/8 in. conversion is especially useful for machines and setups where space is at a premium.

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.
