Tapered Spacers For Line Falls
To Suit ASME Class 150 Piping Systems
Machined to length from a solid PTFE billet, tapered spacers are commonly used in pairs to provide falls in horizontal pipework to allow draining. Please note falls of less than 1 degree can be achieved on site without the need of a tapered spacer. For this reason we don’t offer tapered spacers less than 1 degree.
The minimum thickness of the thinest section does vary on nominal bore but is not less than 4mm.
