First Line 4040 FRP Membrane Housing | 300 PSI End Port

• Test Pressure:
  Each membrane housing is hydrostatically tested at 1.5 × the maximum working pressure to verify structural integrity and sealing performance.

• Working Pressure Rating:
  Tested and rated for continuous operation at 300 PSI or 450 PSI, depending on model.

• Test Medium:
  Clean water at ambient temperature.

• Operating Temperature (Test Basis):
  77°F (25°C)

• Maximum Operating Temperature:
  113°F (45°C)

• Pressure Holding Time:
  Maintained at test pressure for a defined duration to ensure no leakage, deformation, or material failure.

• Leak Integrity Test:
  All ports, end caps, and sealing surfaces are inspected for leaks under pressure.

• Dimensional Verification:
  Internal and external dimensions verified to ensure proper membrane fit and sealing.

• Visual & Structural Inspection:
