Copper compression fittings are one of the most practical and widely used pipe connection methods in Qatar\’s plumbing, HVAC, and medical gas installations. They create a reliable, leak-tight seal without the need for heat, flux, or specialised tools — making them fast to install and particularly valuable where flame cannot safely be used.
Autonex supplies Yorkshire-brand and other certified copper compression fittings across Qatar for plumbing, HVAC, and gas installations.
What are Compression Fittings?
Compression fittings create a watertight joint by mechanically compressing a soft metal olive (ring) around the pipe using the compression nut and fitting body. As the nut is tightened, the olive deforms slightly around the pipe, creating a seal without any solder, adhesive, or sealant.
How to Make a Compression Joint
- Cut the copper pipe cleanly and squarely using a pipe cutter (not a hacksaw)
- Remove any burrs from the pipe end
- Slide the compression nut and olive onto the pipe in the correct order
- Insert the pipe fully into the fitting body
- Hand-tighten the compression nut, then tighten a further 1 to 1.5 turns with a spanner
- Test the joint under pressure — no further tightening should normally be required
Types of Copper Compression Fittings
- Straight Couplers — Joining two pipe lengths end to end
- Elbows (90° and 45°) — Changing direction of the pipe run
- Tees — Branch connections
- Reducers — Connecting pipes of different diameters
- Stop Ends (Caps) — Sealing the end of a pipe
- Tank Connectors — Connecting pipes to tanks and cylinders
- Tap Connectors — Connecting flexible hoses to taps and appliances
Advantages of Compression Fittings
- No heat required — Safe to use near flammable materials and in occupied buildings
- Demountable — Can be disassembled and reused (with a new olive)
- Fast installation — No waiting for solder to cool; immediate pressure testing possible
- Suitable for wet pipes — Can be fitted even when the pipe cannot be fully drained
Applications in Qatar
- Domestic hot and cold water plumbing in apartments and villas
- HVAC chilled water and heating connections
- Medical gas pipelines in Qatar\’s hospitals and clinics
- Natural gas installations (using approved gas-rated fittings)
- Industrial water and process piping
