Hose/Line HVAC: Testing and Inspection

Leakage Testing of A/C Hose With PVC Sheath

This procedure should be used to test for leaks from A/C hoses with PVC sheaths. Use leak detector 951 1207.

Proceed as follows if testing indicates refrigerant leakage from the hose:




1 Cut away tie securing PVC sheath. Remove and discard sheath.
2 Clean hose and connections thoroughly. Wipe with dry cloth.
3 Repeat leak test.
Replace hose if test indicates that leakage is still present.

Only hoses without PVC sheaths are available as spares.
