Hd.Valve Piston

$4.99

Fix Number: FIX10246998
Manufacturer Part Number: 180450-S

This is a manufacturer-approved replacement head valve and is sold independently. It controls the amount of air that enters the cylinder when the trigger is initiated. This action creates an imbalance in pressure between the cylinder and the air reservoir, allowing the head valve to open, firing the piston. The head valve can harden and crack and the valve body itself can break too. This will usually become obvious because air will leak from the gun exhaust. To access this part for the repair, you will need to remove the top cap from the nail gun.

Piston Ring

$4.99

Fix Number: FIX17016268
Manufacturer Part Number: N905972

This is an OEM piston ring and is sold individually. The seal allows pressure in the cylinder when the gun is engaged. The pressure pushes the piston down into the cylinder. This piston ring will deteriorate with time and this seal will loosen. When the piston ring is not sealing as it should, the driver can lose power and not work at all. This is a very simple repair and starts by removing the top cap from the tool. Next, remove the piston and ring. The new piston can now be installed in its place. The new piston ring fits over the top of the piston, just be careful not to damage it.

O-Ring

$4.99

Fix Number: FIX10246996
Manufacturer Part Number: 180448

This is an OEM replacement O-ring for a nailer, sold individually. This O-ring is what seals the cylinder to the housing of the gun and creates separation between the upper and lower air chambers. Due to its rubber material, over time, it can wear. For this repair you will need to remove the cap, disassemble the head valve, remove the spring, and remove the old O-ring. Apply some lubrication to the new O-ring and place it on the valve.

Urethane Retainer

$4.99

Fix Number: FIX10112220
Manufacturer Part Number: 890725

This is a manufacturer approved urethane retainer that is sold individually. The retainer secures the pins in the nailer and are known to deteriorate with use. A damaged retainer can become loose and fall off the pin in which they are retaining. This is a part that should be checked regularly.

Piston,Head Valve

$5.90

Fix Number: FIX10246691
Manufacturer Part Number: 174054

If air is leaking from your nail gun exhaust, you may be in need of a new piston head valve. The head valve is what regulates the air flow into the cylinder. This OEM head valve is sold individually. Over time, the seals on this plastic part can harden and break, and the valve body itself can also break. For this simple repair, start by removing the head from the nail gun, and then remove the worn valve from the head. There will be O-rings on the valve, which should be inspected and removed, this is a good opportunity to assess their condition, and replace them if needed. They are sold separately. You will then remove the steel washer located in the bottom of the head valve. The O-rings can now be reassembled back onto the new part, and you can begin to reinstall everything.

Exhaust Cover

$4.99

Fix Number: FIX10250194
Manufacturer Part Number: P0590000200

This is a black circular exhaust cover for staplers or nailers. This exhaust cover is designed to allow you to direct the air in any direction you want.

To install this part, you will need a hex key or Allen wrench.

Trigger Valve Kit

$36.19

Fix Number: FIX10251035

Please note that two (2) O-rings are included but can also be purchased separately as parts # 106967 and # 86459. O-rings are easily damaged and worn out, causing tool issues, so it\\\'s a good idea to have a backup or two on hand. Only a hammer is needed for this repair.

Assembly,Piston/Driver

$14.35

Fix Number: FIX10246999
Manufacturer Part Number: 180451

This is a manufacturer-approved piston assembly, which includes an assembled piston and driver. The function of the piston is to push the driver down the cylinder, which drives nails into the object being worked on. The most typical reason the piston assembly needs to be replaced is because the driver is damaged. The tip of the driver tends to deteriorate over time, causing the nails to jam. If your nailer is no longer driving nails properly, this should be one of the first things checked, especially if you hit something hard, such as concrete or metal.

Foot,Contact (No Mar)

$4.99

Fix Number: FIX10246935
Manufacturer Part Number: 179760

This is a single non-marking contact foot. This part attaches to the stapler safety plunger to cushion the plunger, so it does not harm your work piece. It is common for this part to get brittle and break off. To remove the damaged contact foot, use a screwdriver to pry it off. Align the new contact foot with the plunger so the notch is pointing towards the rear of the gun and push it into place. Very quick and easy repair.
