JG Speedfit Manifolds are manufactured from stainless steel to the highest standards. A unique feature is that connections to the heating pipe are Speedfit Push-fit, offering much reduced installation time. All manifolds are pre-fitted with brackets, vibration isolation mounts, and an automatic air vent. Flow rate indicators include the means to adjust flow rate and isolate circuit. Can be assembled to suit left or right hand supply depending upon project type. I bought this for a project that was subsequently upgraded to 4 zone. It's brand new in original packaging and has never been used or plumbed in. I can arrange shipping at around £7.50 otherwise collection from near J11 of the.
