When to Use MLCP Tools and Pipe Clips

Use the correct tools and accessories when preparing, bending and supporting MLCP pipe.

Calibration tools, deburring tools and bending springs help with cleaner pipe preparation and routing. Pipe clips help secure pipework to suitable walls, ceilings or boards and keep the installation tidy.

When Not to Use MLCP Pipe Without Checking First

MLCP is versatile, but installers should always check compatibility before using it.

• Do not mix pipe and fittings unless the manufacturer confirms compatibility.
• Do not press fittings with the wrong jaw profile.
• Do not assume U Profile and TH Profile fittings are interchangeable.
• Do not use transition fittings without checking the connection type and pipe size.
• Do not install pipe without preparing the pipe end where calibration or deburring is required.
• Do not exceed the system guidance for temperature, pressure or application.

U Profile vs TH Profile: Why It Matters

One of the most important checks with MLCP systems is the pressing profile.

PressIT and Tweetop Heating/Water fittings commonly use U Profile. Emmeti Gerpex fittings commonly use TH Profile. The pipe, fitting and jaw must be compatible before pressing.

Quick Answer: When Should You Use MLCP?

Use MLCP pipe when you need flexible, easy-to-route pipework for heating, water, cooling, retrofit or distribution systems, especially where long pipe runs, fewer joints, neat routing and compatible press-fit connections are important.

Choose 16mm MLCP for smaller branches and tight routes, 20mm MLCP for medium runs and manifold feeds, and 32mm MLCP for larger distribution pipework and main runs.

Not inserting the pipe fully leads to:

• Weak mechanical joints

• Unpressed fittings

• Leaks over time

Use a depth gauge or marking tool to indicate how far the pipe should be pushed into the fitting.

6. Misalignment Before Pressing

Stress Points and Leaks

Misalignment places unnecessary stress on joints, increasing the risk of:

• O-ring displacement

• Structural fatigue

• Delayed system failure

Ensure the pipe is straight and fully seated before pressing.

7. Over-Pressing or Under-Pressing Fittings

How to Identify Proper Press Strength

Most pressing tools automate the process, but issues still occur due to:

• Low battery on cordless tools

• Manual misjudgement with hand tools

Verify your tool’s pressure settings or upgrade to models with press force feedback.

8. Mixing Brands of Pipe and Fittings

Material Tolerances and Seal Integrity

Brand A’s pipe may not fit Brand B’s fitting—even if they look similar. Mismatching can cause:

• Improper seating

• Seal failure due to size variance

• Legal liability in warranty claims

Stick to one system from a single manufacturer whenever possible.

9. Neglecting Pressure Testing Post-Installation

When and How to Perform Testing

A visual inspection is never enough. Pressure testing is the only way to catch:

• Hairline cracks

• Loose fittings

• Faulty seals

Follow your region’s regulations and manufacturer testing protocols to perform this crucial step.

10. Failing to Inspect O-Rings and Seals

Causes of Premature Seal Failure

Before insertion, always check the O-ring for:

• Dust or debris

• Tears or kinks

• Incorrect placement

Even a tiny imperfection can ruin the seal, especially under high pressure.

11. Installing in Non-Recommended Environments

High Temperature, UV, and Freezing Concerns

MLCP systems aren't one-size-fits-all. Common issues include:

• UV degradation in outdoor installs

• Brittle pipes in freezing climates

• Melting or expansion in high-heat zones

Always review the environmental limits for the selected pipe system.

12. Lack of Training or Certification

Why Hands-On Experience Matters

Many fitting systems require certified training. DIY installs or untrained professionals often:

• Use the wrong tools

• Misinterpret instructions

• Skip vital steps like pressure testing

Invest in a certification course to future-proof your skills and ensure professional-quality work.
