Straight Connections for Hydraulic Pumps

Straight connections for hydraulic pumps are key fasteners enabling efficient and failure-free connection of the pump with pressure lines (discharge) and suction lines. A properly selected connection ensures full throughput of the hydraulic system and eliminates the risk of oil leaks under high pressure.

Solid Construction and High Tightness

The offered straight connections are made of high quality galvanized steel or aluminum alloys, which guarantees their exceptional mechanical strength as well as resistance to corrosion and harsh working conditions in industrial, agricultural, and construction machinery.

Each pump connection is supplied as a complete kit ready for assembly, containing:

• Connection body: with an appropriate outlet for metric or inch (BSP) threads.
• Set of bolts and washers: allowing for secure bolting of the flange to the pump body.
• Sealing O-ring: made of rubber resistant to mineral oils and hydraulic fluids, ensuring 100% connection tightness.

Compatibility with DKOL and DKR Fittings

Straight connections most commonly feature metric or inch (BSP) threads with sealing cones (e.g., 24° or 60°), which work perfectly with standard fittings crimped on hydraulic hoses: **DKOL / DKOS** (metric threads) and **DKR** (inch BSP threads).

When is it Worth Replacing a Pump Connection?

Although many hydraulic pumps have factory ports, their replacement is necessary in case of system expansion, change in hose diameter, thread damage, or replacement of the pump itself with a model having a different mounting bolt spacing.
