DRAIN VALVE
Part #N286039
When using an air compressor, moisture naturally builds up inside the tank as air is compressed. If this water isn’t drained regularly, it can lead to internal rust and damage over time. That’s where the drain valve comes in—it allows you to release the built-up water and keep your tank in good condition. Located at the bottom of the tank, this valve should be opened after each use to prevent corrosion and extend the life of your compressor. If you tend to leave air in the tank for long periods, water accumulation can be even more significant. This replacement drain valve features a thread size of 18 TPI and is sold individually. Regular maintenance with a working drain valve helps ensure safe and efficient compressor operation.

Disassemble plastic housing around compressor unit using appropriate tools. Remove the four bolts from the compressor head using a 5/16 nut driver. Carefully remove head assembly including airline. Remove bolt through rod bearing with Allen wrench.

Reassemble with new rod and piston assembly. Best to use blue locktite on bolt through rod bearing when reassembling. Make sure to torque all bolts to specs listed.
