Hydraulic Accessories And Fittings

// About Our Products

Hydraulic accessories and fittings are essential components used to support, protect, and improve the performance of hydraulic systems. They ensure clean oil flow, proper pressure control, safe connections, and long service life of hydraulic equipment.

Suction Filter

A suction filter is installed on the pump suction line to protect the hydraulic pump from contamination.

Key Points

Oil Level Indicator (Level Gauge)

An oil level indicator is used to visually check the hydraulic oil level in the reservoir.

Key Points

Bell Housing

Bell housing is used to connect an electric motor to a hydraulic pump with accurate alignment.

Key Points

Return Line Filter

A return line filter cleans the hydraulic oil before it returns to the tank.

Key Points

Pressure Relief Valve

A pressure relief valve protects the hydraulic system from excessive pressure.

Key Points

Check Valve (Non-Return Valve)

A check valve allows hydraulic oil to flow in only one direction.

Key Points

Flow Control Valve

A flow control valve is used to regulate the flow rate of hydraulic oil.

Hydraulic Fittings

Hydraulic systems rely on a variety of precision-engineered fittings and sealing accessories to maintain high-pressure integrity and leak-proof connections. These components, typically made from carbon steel, stainless steel, or brass, are categorized by their shape (Straight, Elbow, Tee) and their specific connection standard (GE, SP, JIC, etc.).

Hydraulic Sealing Accessories

Sealing is critical for preventing fluid loss under high pressure and vibration.

Copper Washer: A malleable sealing ring that adapts to mating surfaces. According to Nafees Metal Industries, these are widely used in high-temperature mechanical setups and hydraulic systems for corrosion-resistant sealing.
Dowty Washer (Bonded Seal): A precision-engineered component consisting of a metal ring bonded to an elastomer sealing element. Experts at Excellent Hydraulics note that these are essential for leak-proof joints in high-pressure systems where vibration and pressure fluctuations occur.

Standard Hydraulic Fittings

Fittings are the primary connectors used to route fluid through hoses and pipes.

Straight Fitting (Straight Coupling/GE): Used for straightforward pipe or hose extensions., GE refers specifically to a Male Stud Coupling.
Elbow Fitting (90 Degree/WE): Facilitates 90-degree directional changes.
Tee Fitting (T-Type/TE): Allows for branch connections in three directions. Popular options include the Hydraulics Direct Branch Tee made from pressure-resistant carbon steel with a zinc-trivalent anti-corrosion coating.
SP Fitting (Stand Pipe Adapter): A specialized adapter used to connect a tube to another fitting or port using a standpipe design.

GE Fitting (Straight Male Connector)

A GE fitting is used to connect hydraulic hoses to valves, pumps, or manifolds.
