How to Use Yorkshire Fittings
Yorkshire fittings produce a cleaner connection than standard solder fittings. (plumbing image by Inger Anne Hulbækdal from Fotolia.com)

Sealing a soldered copper connection requires the correct use of heat, flux and solder. Incorrectly flowing solder into a copper plumbing connection causes water leaks that are time consuming to fix after the line fills with water. A Yorkshire fitting eliminates the guess work involved in soldering a copper connection by having the solder adhered to the inside surface of the fitting. When the Yorkshire fitting is fitted and heated, the solder melts and fills the void in the copper joint.

Instructions

  1. 1

    Clean the inside of the Yorkshire fitting and the outside of the copper pipes entering the connection with 220-grit emery cloth until all surfaces are shiny.

  2. 2

    Apply an even coat of soldering flux to the cleaned portions of the Yorkshire fitting and the copper pipe with an acid brush.

  3. 3

    Push the Yorkshire fitting onto one cleaned side of copper pipe until you feel the pipe seat against the fitting's internal pipe stop. Slide and seat the second length of copper pipe into the fitting using the same method.

  4. 4

    Heat the Yorkshire fitting with a lit plumber's torch. Hold the torch tip two inches from the surface of the fitting while you heat the entire surface of the fitting, starting from the centre of the fitting and working toward each end.

  5. 5

    Stop heating the Yorkshire fitting when you see a solid silver bead of solder around both ends of the fitting. If you notice one side of the fitting has a solder bead, heat the other side of the fitting until the silver ring appears.

  6. 6

    Allow the Yorkshire fitting to cool to room temperature before handling the soldered connection or insulating the pipe.

Tips and warnings

  • Heat a Yorkshire fitting only after copper pipe is fitted into both sides of the fitting.
