Eaton KP77434 Air Hose 400 Psi 1/4 Inch Id 50 Feet

Product Description

The EATON KP77434 is a 50-foot compressed air hose built for demanding pneumatic applications in trade and industrial environments. Constructed from Buna-N nitrile rubber, this hose handles a working pressure of 400 psi with a 1/4-inch inside diameter and a 0.5-inch outside diameter. The nitrile rubber construction resists oils, fuels, and abrasion, making it a dependable choice for air tool operation, compressor hookups, and general-purpose pneumatic lines. Licensed tradespeople and service technicians working in HVAC, plumbing, and industrial service regularly rely on hoses of this specification for day-to-day field work.

This hose is suited for use with 1/4-inch pneumatic fittings and air tools in both residential and commercial service settings. The 50-foot length provides working range from a stationary compressor without repeated repositioning. At 400 psi working pressure, it supports most standard air-powered tools including impact wrenches, ratchets, drills, and blow guns. The Buna-N material performs reliably across a range of shop and field temperatures and resists degradation from incidental oil and lubricant contact common in compressor-fed systems.

Key Features

• 400 psi working pressure rating for heavy-duty pneumatic use
• 1/4-inch inside diameter compatible with standard 1/4-inch pneumatic fittings
• 50-foot length provides extended reach from a fixed compressor location
• Buna-N nitrile rubber construction resists oil, fuel, and abrasion
• 0.5-inch outside diameter for a compact, manageable profile

Compatibility

Designed as a general-purpose replacement or service hose for pneumatic systems using 1/4-inch ID air line connections rated at or below 400 psi working pressure.

Installation Notes

Installation and replacement of compressed air hoses should be performed by a qualified technician familiar with pneumatic system safety. Always depressurize the air line and bleed residual pressure before disconnecting any fittings. Inspect fittings and couplers for wear or damage before connecting the hose to a compressor or air tool. Ensure all connections are fully seated and rated to match or exceed the 400 psi working pressure of this hose.
