Begin with a meticulous inspection to lay the groundwork for a leak-free connection.
Part Inventory: Confirm all components listed in the packaging are present.
Damage Inspection: Scrutinize the fitting body, seals, and fasteners for any evidence of shipping damage, corrosion, or manufacturing defects.
Dry Run Alignment: Gently mate the connection ports without tightening to check for perfect alignment and avoid cross-threading or port misalignment.
HAND HYDRAULIC Pro Tip: A minute spent on inspection can prevent catastrophic downtime. Never install a component that fails this initial check.
Reduce on-site complexity by pre-assembling components in a controlled environment.
Carefully install seals, backup rings, and nuts onto the fitting body as designed.
Ensure all parts seat smoothly and snugly. Use a recommended lubricant compatible with your hydraulic fluid to aid assembly and prevent seal damage.
HAND HYDRAULIC Pro Tip: Proper sub-assembly minimizes contamination and error risk during the final installation in often cramped system spaces.
This is where technical precision is paramount. Improper torque is the leading cause of fitting failure.
Follow a Sequence: Use a crisscross or star pattern, tightening bolts in multiple stages (e.g., 30%, 60%, 100% of final torque) to ensure even flange pressure and avoid gasket distortion.
Respect the Torque Specification: Overtightening is dangerous. It can strip threads, crush seals, and create stress fractures, leading to sudden failure under pressure.
HAND HYDRAULIC Pro Tip: Always use a calibrated torque wrench. We provide specific torque values with our products to guarantee a seal without compromising component integrity.
After tightening, check the fitting's final position within the hydraulic circuit.
Ensure the fitting and connected hoses or tubes are aligned naturally, with no bending moments or torsional stress imposed on the connection.
A stress-free installation is essential for achieving the designed cycle life of the components.
This final step is your quality assurance checkpoint before system commissioning.
Pressure Test: Gradually raise the system pressure to its operational level while checking for any sign of leakage at the fitting.
Post-Test Re-check: After depressurizing, perform a final check on all fasteners to confirm they have not loosened due to thermal cycling or initial settling.
