Extra regulators and Changeover Device

Here is a range of good quality regulators for high pressure (more than 0.5 bar - 7 psi), and low pressure (28 mbar to 37 mbar), and also a changeover valve.

If there is not a regulator here for your needs please contact us and we will try to find it for you.

Please note that Flashback arrestors are not needed when propane is used on its own. This is true for Bullfinch propane gas burning appliances. Flashback arrestors are required for oxy-propane and oxy-acetylene systems and for the Bullfinch Autotorch for acetylene.

Low pressure appliances

Traditionally most low pressure appliances in UK operate at 28/29 mbar with butane and 37 mbar with propane. This is category I3+. General portable appliances like patio heaters, barbecues, boiling rings, hotplates will operate off either supply but care needs to be taken to read the instructions as there may be some variation in this.

New caravans and some other environments now have to be supplied with special regulators that are rated at 30mbar whether propane or butane is used. This is category I3B/P. Built in appliances will be made for this pressure and they may not work satisfactorily on a I3+ supply. Portable appliances will generally work satisfactorily off this supply for example using our Gas/barbecue point no. 6087/01.
