Description QS20079

The QS20079 injector O-ring puller is a specialized tool for workshops servicing diesel engines. This puller is designed to solve a common problem: removing copper O-rings that are located at the bottom of the injector well and often stuck tightly due to carbon deposits. It has a length of 350 mm and a built-in reverse hammer.

Trying to remove the old copper ring with improvised means often leads to damage to the seat, falling debris into the cylinder, and the inability to install the new injector tightly. The QS20079 completely solves this problem: the conical threaded tip screws into the copper ring, securely gripping it, and the reverse hammer allows you to remove the ring in seconds. There are no moving parts that could fall into the engine.

Specifications

⚠️ Important: Before use, make sure that the injector well is clean of carbon deposits. After removing the old ring, be sure to install a new original seal.

When to use this puller

• When replacing diesel injectors to remove old copper rings.
• When the copper ring is stuck to the seat due to carbon deposits.
• To clean the injector well before installing a new one.
• On Common Rail and conventional diesel engines.

Advantages of QS20079

Precise Grip

The tapered threaded tip screws securely into the copper ring, ensuring a strong grip.

Reverse Hammer

The built-in hammer allows you to remove even heavily coked rings without unnecessary effort.

Engine Safety

The absence of small moving parts prevents tool elements from falling into the cylinder.
