The 29mbar screw-on butane regulator is the low pressure fitting designed for the Calor 4.5kg butane cylinder. It’s part of the Calor Essentials range, and it screws onto the cylinder valve, stepping the butane down to the working pressure the appliance is built for.The screw-on connection is what sets it apart from the clip-on butane regulators. The 4.5kg butane bottle takes this screw-on type, while the larger 7kg and 15kg butane cylinders use a 21mm clip-on instead, so it’s worth matching the regulator to the bottle you actually have.It suits small butane appliances run from a 4.5kg cylinder. If your appliance specifies a different connection or pressure, this won’t be the right part, so check before you order.Follow Calor’s own guidance on fitting, and if there’s any doubt about the right regulator, a quick call saves a wasted order.

It’s the screw-on type, so it suits that bottle rather than the larger 7kg and 15kg butane cylinders, which take a 21mm clip-on regulator instead. Check it matches your cylinder valve and appliance before use.Is this a screw-on or clip-on regulator?It’s a screw-on regulator, so it threads onto the 4.5kg butane cylinder valve rather than clipping on. If your butane bottle uses a clip-on valve, you’ll need a clip-on regulator instead, so check the valve type before ordering.Do you deliver gas regulators to my area?We deliver across a defined set of postcodes around Reading, Berkshire and into parts of South Oxfordshire and Buckinghamshire.
