Product questions
What does the Index 8040177 pressure switch do?
It is a normally closed high-pressure cutout switch for an R134a air-conditioning system. Its listed rising-pressure set point is 300 psi; high-pressure cutout switches interrupt the compressor circuit when pressure becomes excessive.
What is the reset pressure of the Index 8040177?
Index documentation conflicts: its product catalog lists a 300 psi reset, while its APAds FAQ lists a 300/260 psi pressure setting. Confirm the required reset point before ordering rather than assuming either value.
What fitting and electrical connector does the 8040177 have?
The Index catalog lists an M10 female Schrader fitting and a Metri-Pack connector. Compare both connections with the existing switch before ordering; thread pitch is not specified in that catalog.
How can I check whether the 8040177 fits my equipment?
Fitment cannot be established from a model name alone. Provide the equipment serial number, existing switch number and A/C system details, and verify the fitting, connector and pressure settings before ordering.
