John Guest Speedfit


JG Speedfit is a push-fit system suitable for the air and water flow of normal agricultural hot and cold water services and central heating applications, including pressurised and combi systems.

Speedfit fittings have been designed for use with both Speedfit and Copper pipe, in diameters 10mm and 1/2” to 1” Irish. They are approved by the Irish Board of Agrément and WRAS and are kite marked to BS7291 Parts 1, 2 and 3, Class S, (Licence No. KM 39767).
Performance specifications are well within those required for most normal domestic central heating and water supply systems including:
  • Mains fed and indirect cold water systems.
  • Vented and unvented hot water systems.
  • Vented central heating systems.
  • Sealed central heating systems provided temperatures and pressures comply with BS7291 Parts 1, 2 and 3 Class S.
  • Underfloor heating.
Extensive tests have shown that Speedfit products will Withstand temperatures and pressures well in excess of Normal working conditions.

  • Truly demountable without damage to pipe or fitting.
  • Grip and seal connection.
  • Super seal Insert gives secondary seal.
  • Reduced pipe insertion force.
  • Lightweight and easy to handle on site.

  • Installation time reduced by up to 40%.
  • Pipe flexibility permits the cabling of pipe through
  • less accessible areas.
  • No risk of fire or flames from a blowtorch.
  • Easier to work in confined places.
  • A permanent leak-proof connection.
  • Corrosion free.
  • No scale build up.
  • Lower thermal diffusivity maintains safer surface temperature.
  • Pipe elasticity can reduce the possibility of bursting under freezing conditions.
  • Lead free and nontoxic.
  • Less noise from water flow and expansion/contraction.
  • Long pipe lengths reduce fittings required.


Speedfit Fittings have a unique grip then seal construction made up of a collet with stainless steel teeth to grip the pipe and an ‘O’ ring to provide a permanent leak proof seal.

An ‘O’ ring at the head of the insert and the shape of the stem, provide a secondary seal against the bore of the fitting. A combination of this and the main ‘O’ ring ensure a good connection. The stem of the insert gives greater rigidity of the length of pipe within the fitting, reducing the chance of leaks if a side load is applied.

The head of the insert has been designed for ease of insertion. The additional benefit of Twist and Lock Fittings is that a twist of a Screw cap locks the pipe in position and gives increased compression on the ‘O’ ring for even greater security.
