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.

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.
