Difference Between Single and Double Compression Fitting

Single Compression Fitting

Single and Double Compression Fitting also known as Single ferrule and Double ferrule fitting. Single ferrule Fitting have less pressure rating compare to Double ferrule fitting. 316 stainless steel or brass Compression Fittings are most popular grade in industrial plants and suitable to use in suitable the applications performed in high pulsation and vibration conditions. Single ferrule tube fittings are available in 1/16 to 2 inches sizes. These fittings can not be installed incorrectly because of their special design. These fittings are made from less pieces than most other types of fittings.

Double Compression Fitting

Double ferrule are available in various materials such as Stainless Steel, Copper, Brass, Monel, Inconel, Duplex Steel etc. These Double Compression Fitting are known for its consistent leak-tight connections, due to strong mechanical grip.

These Fitting are suitable to used for thick- and thin-walled tubings as well as hard and soft tubings.

Benefit to use Single Compression Fitting

  • No backward movement- Single ferrule means only a single direction, hence ensures correct installation.
  • Single ferrules are easy to install as not installing a ferrule would be hard to miss. there is very less chance of assembly errors compared to double ferrule fittings.
  • Some instruments or facilities have been made using single ferrule fittings. wehich enable it to use single ferrule designs for replacements
  • Under certain conditions, single ferrule fittings prove to resist better vibration and pulsation.

Features of Double Compression Fitting

  • Highly corrosion and chemical resistant
  • Can withstand extreme temperatures
  • Highly pressure resistant. Even in harsh or high-stress nuclear environments 
  • Offer maximum strength and ductility
