This is a rubber O-ring for a compressor. It creates a seal for the tube as it enters the head. This part is sourced directly from the original manufacturer, ensuring it is the correct fit. It measures approximately 0.362 in inner diameter and 0.103 in outer diameter. Over time, the O-ring can begin to wear and should be replaced to maximize the power of your air compressor. Before you begin this repair, you will need to unplug the unit and bleed air from the tank.

This is a valve plate for your compressor or generator. This part controls the air flow into the pump. When the air is pumped by the piston, it passes through the valve plate and into the compressor tank. The most common sign of a damaged valve is if your pressure is not building up in the tank. The reeds on the valve plate are usually the first thing to wear out. If you notice visible damage on the reeds you will need to replace this part. This valve includes the plate, and the lower gasket. The head gasket is sold individually.

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: • <u>Extrusion and Nibbling</u> - 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. • <u>Abrasion</u> - 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. • <u>Over Compression </u> - The O-ring is flattened on both sides and may have a "ring" split along its length. Commonly caused by excessive pressure or heat. • <u>Heat Hardening</u> - The O-ring has a pitted or cracked surface, and is often flattened on both sides. Caused by temperature exceeding o-ring capacity. • <u>Weather/Ozone Cracking</u> - 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.

This is a manufacturer-approved head gasket for an air compressor, sold individually. It is designed to seal the valve plate to the cylinder head. If this gasket is damaged or worn, this can create an air leak from the head, which will make it so the compressor is no longer pressurizing the tank. For this repair you will need the following tools: Philips screwdriver, torx drivers, flat-blade screwdriver, long-nosed pliers, impact driver or socket wrench, and a torque wrench.

Genuine OEM replacement parts kit. This Gasket Kit is used to prevent air leaks in the compressors listed below. Over time the gaskets will become compressed or cracked and you will hear an air leak coming from the compressor. They will need to be replaced. This would be a good time to inspect all the other wear parts of the compressor.

This O-ring is compatible with various models of compressors made by DeWALT, Black & Decker, and Bostitch. It is an authentic replacement part from original manufacturer. An O-ring is used to prevent pressure loss between joined rigid parts by creating a seal. Many tools require working O-rings in order to function. Please check that the correct O-ring is being used in the correct position, as many tools use multiple different O-rings throughout. Sold individually.
