DRAIN VALVE – Part Number: N286039

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.

ORING P/L HEAD
Part #ACG-45
O-rings are made to contain thousands of PSI pressure by creating a seal between two or more parts. O-ring measurements are defined by the inside diameter and the thickness. rnrnThere are many causes for O-Ring failure. The most common among power tools are: • Extrusion and Nibbling - The O-ring has ragged, tattered edges. These are commonly caused by pressure spikes which shear off tiny "bites" from the o-ring, or caused by clearance gaps. • Abrasion - One or both sides of the o-ring appear rough and slightly flattened. Commonly caused by a contact surface that it too rough, contains grit or is too smooth to allow lubrication. • Over Compression - The O-ring is flattened on both sides and may have a "ring" split along its length. Commonly caused by excessive pressure or heat. • Heat Hardening - The O-ring has a pitted or cracked surface, and is often flattened on both sides. Caused by temperature exceeding o-ring capacity. • Weather/Ozone Cracking - The O-ring is covered in small surface cracks. Caused by exposure to ozone, UV rays and air pollution. Excessive seal stretching (greater that 5%) causes similar cracking.
