Most of our vented copper cylinders come as industry standard Part L, suitable for 10m working head, and have to be lagged.

This is our range of grade 3, grade 2 and grade 1 cylinders which can all be shipped without lagging (they can, of course, be lagged). The thickness of copper increases the lower the grade:

Grade 3 test pressure is 1.45 bar and is suitable for 10m working head

Grade 2 test pressure is 2.2 bar and is suitable for 15m working head

Grade 1 test pressure is 3.65 bar and is suitable for 25m working head
