What Is A Compression Connection?

A compression joint creates a secure, yet demountable, seal by compressing an olive (inner-ring) against a pipe. The joint consists of three main components: a compression nut, an olive, and the fitting body. When the nut is tightened, it compresses the olive against the pipe, forming a seal that prevents leaks and holds the connection firmly in place, allowing a smooth flow of liquids or gases.

Where Are Compression Fittings Used?

Compression Fittings are versatile and used across numerous industries to connect tubes or pipes of various materials. Being demountable, they are an easy choice for systems that need to be maintained regularly.

They are commonly found in:

• Automotive sector

• Domestic and Commercial HVAC systems

• Oil & Gas

• Low-pressure gas installations

• Various industrial services

PEX compression Fittings

Compression PEX Fittings, typically sized from 16mm, are designed specifically for use with PEX (cross-linked polyethylene) Pipes. Made from brass, these fittings create a watertight seal by inserting a spigot inside the PEX pipe and using a split ring olive to bite into the outer wall of the pipe. Ideal for plumbing, heating, underfloor heating and potable water systems, they provide a reliable, flame-free connection without the need for special tools or heating.

Raccordi PEX

I raccordi Flowflex PEX offrono connessioni affidabili tra ottone e PEX per diverse esigenze idrauliche. Disponibili nelle dimensioni 16 mm e 20 mm, garantiscono qualità e durata per sistemi idrici, riscaldamento centralizzato e riscaldamento a pavimento. Questi raccordi consentono un'installazione semplice, senza calore, e sono compatibili con tubazioni bagnate. Conformi alla norma BS EN 1254-3 e coperti da una garanzia di 25 anni, i raccordi Flowflex PEX assicurano prestazioni durature. Clicca per saperne di più sulla nostra gamma.

What Are The Advantages Of Compression Fittings?

1. Heat-Free Connections
   Compression fittings do not require soldering or welding, making them ideal for construction sites where hot works are restricted or where open flames are not safe.

2. Ease of Assembly
   Compression joints are easy to understand and install, making them suitable for both DIYers and professionals. Simply slide the pipe into the fitting, add the olive, and tighten the nut.

3. No Special Tools Needed
   Only basic tools, like adjustable spanners, are required to install compression fittings - no expensive or specialised equipment necessary.

4. Easy to Disassemble
   If maintenance or disassembly is needed, compression fittings can be undone and reassembled without damaging the connection.

5. Reusable Components
   Compression fittings can be reused in future installations. Simply replace the olive with a new one from the same manufacturer, as the old olive remains fixed to the original pipe.

6. Installation in Wet Conditions
   These fittings can be installed in wet environments, speeding up repair times and making them ideal for leak fixes.

7. Environmentally Friendly Materials
   Copper alloys are sustainable and recyclable materials, making Compression Fittings an environmentally friendly option.

8. Compatible With Multiple Types of Pipe
   Compression fittings are not limited to copper; they work with plastic, carbon steel, and stainless steel pipes, making them adaptable to multiple systems.

Considerations

Over-tightening

Over-tightening can damage the olive or pipe. Tighten until the nut stops with reasonable force, and avoid turning further.

Stress Corrosion Cracking (SCC)

SCC can occur in brass components exposed to tensile stresses and corrosive environments, often due to over-tightening or contamination. Proper installation practices prevent SCC; read more in our article on SCC for detailed guidance.

Conclusion

For a quick, cost-effective, and reliable connection, compression fittings are unbeatable. If you want to learn more about compression fittings or need assistance, explore our product range or contact us directly for support.
