Stellar Industries 16404 45-Degree Hydraulic Pump Suction Fitting – 1.25"

If you’re unsure whether this part is compatible with your truck or equipment, please contact us to confirm fitment before purchasing.

The Stellar 16404 Hydraulic Pump Suction Fitting is an OEM 45-degree inlet fitting designed for compatible VOAC and Parker hydraulic pumps. Its angled design provides a smooth connection between the hydraulic suction hose and pump inlet where installation space is limited.

The 1.25-inch connection supports unrestricted oil flow into the pump, helping prevent suction-line restriction, cavitation, and premature pump wear.

What This Part Is Used For

The Stellar 16404 fitting connects a 1.25-inch hydraulic suction line to the inlet of a compatible VOAC or Parker pump. The 45-degree angle helps route the hose away from surrounding equipment while reducing sharp bends in the suction line.

Common Reasons For Replacement

Hydraulic fluid leaking at the pump inlet
Cracked or damaged fitting body
Damaged threads or sealing surface
Corrosion around the connection
Distorted fitting caused by overtightening
Restricted flow from an incorrect fitting
Changing the pump or suction-hose configuration
Damage during pump removal or installation
