Sponsored Walk


Our factory manager Kevin Hempsall who has been with us for 27 years has recently been featured in the local news for his efforts in raising money to support his now retired colleague after a life changing operation. On the 4th of August, Kevin will walk 34 miles from his house in North Hykeham to Cadwell Park Race Circuit. The walk comes on the heels of his 44 mile walk from his house to Skegness in December of 2017 which he completed in 11 hours. We wish Kevin the best of luck.

Our Vision

We have always embraced the idea of making all of our products by hand; not only does this allow us to constantly ensure our units are of the highest quality and free from defects but also allows us to tailor our units to the customers exact requirements.

We also pride ourselves with our attitude towards customer service; we do not outsource or hire a dedicated customer service department, instead all our office staff are knowledgeable through industry experience and can give much more personalised customer service; the flat nature of our company's hierarchy also means when you call you can even be put straight in touch with a managing director.

Why buy from Newark Copper Cylinder?


As customers may have existing pipework or systems in place, we understand ease of installation is a necessity; we are able to design and manufacture a unit to suit any existing pipework.


We supply a large range of units to meet customers needs such as custom heights and diameters, fitting size and placement, inputs and outputs, coils and material.


As we are aware that customers can be in need of a replacement unit urgently, we are able to manufacture units as early as the same day, and can be delivered for the following day.
