Atlas Copco Pipe Seal Kit Replacement – 2906001200

Atlas Copco 2906001200 – Pipe Seal Kit

The Atlas Copco 2906001200 (2906-0012-00) is a Pipe Seal Kit designed for servicing the applicable piping and connection points of Atlas Copco air compressors.

The kit is used during maintenance to replace worn or deteriorated sealing components in compressor pipe connections. Proper sealing is essential because compressed-air systems operate under pressure, and even small leaks can result in pressure loss, increased compressor loading and unnecessary energy consumption.

Working Process:

During normal compressor operation, air is compressed and transported through various internal pipes and connections.

The pipe connections must remain properly sealed to prevent compressed air from escaping.

Over time, seals can deteriorate because of:

• Pressure cycling
• Temperature changes
• Vibration
• Ageing
• Oil exposure
• Mechanical movement
• Improper previous installation

When a seal deteriorates, compressed air may leak through the pipe connection.

The 2906001200 Pipe Seal Kit is used during scheduled maintenance to replace the applicable sealing components.

The old seals are removed, the sealing surfaces are cleaned and inspected, and the replacement seals are installed at the designated pipe connections.

Once the connections are correctly reassembled and tightened, the new seals create a leak-tight barrier.

This restores the integrity of the piping circuit and helps the compressor maintain the required pressure efficiently.

Main Functions:

• Provides replacement sealing components for compressor piping.
• Restores sealing at pipe connections.
• Helps prevent compressed-air leakage.
• Helps maintain system pressure.
• Supports efficient compressor operation.
• Reduces unnecessary compressor loading.
• Helps reduce energy losses caused by leakage.
• Supports reliable compressor performance.

Part Information:

Part Number: 2906001200
Alternative Number: 2906-0012-00 / 2906 0012 00
Brand: Atlas Copco
Description: Pipe Seal Kit / Service Kit
Component Type: Pipe and connection sealing service kit

Parts references specifically identify 2906001200 as a Pipe Seal Kit.

A separate application listing identifies the same part number as a seal service kit for an Atlas Copco ZT30 compressor.

Pipe-Sealing Operating Principle:

1. Compressed-Air Generation: The compressor produces compressed air.
2. Air Transfer: Compressed air travels through internal piping.
3. Connection Sealing: Seals prevent air from escaping at pipe joints.
4. Pressure Maintenance: Proper sealing allows the system to maintain operating pressure.
5. Continuous Operation: The seals remain exposed to pressure, temperature and vibration during operation.
6. Maintenance: Worn seals are replaced using the service kit.
7. Leak Testing: The repaired connections are checked for leakage before returning the compressor to normal service.

Importance of Pipe Seals:

A compressor piping system must remain leak-tight to maintain efficiency.

A damaged seal can cause:

• Compressed-air leakage.
• Pressure loss.
• Increased compressor running time.
• Increased energy consumption.
• Poor system pressure stability.
• Increased operating costs.
• Reduced compressor efficiency.
• Possible contamination around leaking connections.

Even a relatively small leak can become significant when the compressor operates continuously.

Typical Seal Failure Causes:

Pipe seals may deteriorate because of:

• Normal ageing.
• High temperature.
• Pressure cycling.
• Compressor vibration.
• Oil exposure.
• Incorrect seal installation.
• Over-tightening.
• Under-tightening.
• Contaminated sealing surfaces.
• Damaged pipe or fitting surfaces.

Maintenance Procedure:

Before servicing the pipe connections, shut down the compressor according to the applicable Atlas Copco procedure.

Isolate the electrical supply and depressurize the compressor.

Allow hot components to cool to a safe working temperature.

Identify the pipe connections requiring service.

Inspect the connections for:

• Air leakage.
• Oil contamination.
• Damaged seals.
• Corrosion.
• Damaged threads.
• Scratched sealing surfaces.
• Loose connections.

Remove the old sealing components.

Clean the mating and sealing surfaces thoroughly.

Install the appropriate replacement sealing components from the 2906001200 Pipe Seal Kit.

During installation:

• Use the correct seal at each connection.
• Do not stretch or damage sealing elements.
• Ensure seals are correctly seated.
• Keep sealing surfaces clean.
• Avoid twisting or pinching seals.
• Tighten connections according to the applicable Atlas Copco service procedure.

After assembly, perform a suitable leak test.

Restart the compressor and allow it to reach normal operating pressure.

Inspect the serviced connections again for:

• Air leakage.
• Oil leakage.
• Pressure instability.
• Abnormal vibration.
• Abnormal operating conditions.

Service Benefits:

Using the Atlas Copco 2906001200 Pipe Seal Kit during appropriate maintenance helps:

• Restore leak-tight pipe connections.
• Reduce compressed-air losses.
• Maintain system pressure.
• Improve compressor efficiency.
• Reduce unnecessary compressor loading.
• Reduce energy waste.
• Support reliable compressor operation.
• Reduce the risk of unexpected downtime.
