36" Length • 1" Inside Diameter • Internal Wire Reinforcement • Includes Two T-Style Hose Clamps

Replace a worn, cracked, or leaking hydraulic suction hose with the WSD31-077 36" Suction Hose. Designed for the low-pressure suction side of compatible hydraulic systems, this heavy-duty hose features a 1-inch inside diameter, internal wire-frame reinforcement, and a full 36-inch length that can be used as supplied or cut to fit your application.

Two premium T-style hose clamps are included, making this a convenient replacement for log splitters and other equipment using compatible mechanical gear-pump suction systems. Tool Tuff specifically identifies this hose for suction-side use only—it must not be pressurized.

Key Features & Benefits

• 1" Inside Diameter
  Designed for compatible hydraulic suction systems requiring a 1-inch ID hose.
• 36" Overall Length
  Provides three feet of hose for replacement installations and custom routing.
• Cut to Custom Length
  The hose can be trimmed when a shorter section is required for a particular installation.
• Internal Wire-Frame Reinforcement
  Internal wire support helps prevent the hose from collapsing under suction from the hydraulic pump.
• Two T-Style Hose Clamps Included
  Comes with two premium clamps for securing the hose to compatible fittings.
• Ideal for Log Splitter Hydraulic Systems
  Well suited for replacing the reservoir-to-pump suction hose on compatible hydraulic log splitters and similar equipment.
• Designed for Mechanical Gear Pumps
  Tool Tuff specifically lists the hose for suction use with mechanical gear pumps.

Designed for Hydraulic Suction Applications

Hydraulic gear pumps require a dependable supply of oil from the reservoir. A damaged or collapsing suction hose can restrict fluid flow and interfere with normal hydraulic-system operation.

The WSD31-077 incorporates an internal wire support to help the hose maintain its shape while the pump draws hydraulic fluid from the tank.

Typical applications may include:

• Hydraulic log splitters
• Hydraulic power units
• Equipment using mechanical gear pumps
• Reservoir-to-pump suction connections
• Replacement or custom hydraulic suction routing

Exact compatibility depends on hose diameter, routing, fittings, and equipment configuration.

Quick Specifications

1" ID, 36" length, internal wire support, two included T-style clamps, and suction-only application for part number 31-077. 

Package Contents

• 1 × 36" suction hose with 1" ID
• 2 × T-style hose clamps

Important Installation Information

Before ordering, verify:

• Existing hose inside diameter is 1"
• Required hose length is 36" or less
• Pump inlet and reservoir fittings accept 1" ID hose
• Hose routing does not create sharp bends or kinks
• The connection is on the suction side of the hydraulic system

The hose may be cut to a shorter custom length when necessary.

Suction Side Only — Do Not Pressurize

This hose is designed for suction use only and should not be installed on a pressurized hydraulic line. Tool Tuff specifically states that the 31-077 is intended for mechanical gear-pump suction applications and should not be pressurized.

Do not use it as a high-pressure pump-to-valve, valve-to-cylinder, or other pressure-side hydraulic hose.
