Compression Fittings

Compression fittings join pipe or tubing without heat or solvent by tightening a nut that compresses a ferrule (olive) onto the pipe to seal. They allow quick, reusable connections and are common for water supply, tubing, and appliance hookups.

⚠️ Note: Soft/plastic tubing usually requires a pipe insert to prevent collapse under the ferrule. Over-tightening can damage the ferrule and cause leaks; tighten per manufacturer guidance.

FAQ

Do compression fittings need soldering or glue?

No — they seal mechanically by compressing a ferrule (olive) as the nut is tightened, so no heat or solvent is required. This makes them reusable and suitable for tight spaces.

Can compression fittings be reused?

The body can usually be reused, but the ferrule/olive often deforms and may need replacing to reseal reliably. Follow the manufacturer's guidance and check for leaks after reassembly.
