We keep every size of white flexi in imperial sizes.
Hot tub flexi pipe manufactured in the USA is always measured in inches and is always the internal diameter.
We keep 2" and 1-1/2" in either 1metre lengths or by the 15metre roll.
1/2" 3/4" and 1" we sell off the roll.
These measurements detail the outside diameters, in mm, of white flexi pipe :
1/2 inch = 21.34 mm
3/4 inch = 26.67 mm
1 inch = 33.40 mm
1-1/2 inch = 48.26 mm
2 inch = 60.33 mm
Note - we do not sell rigid pipe, there is no need since we stock 1-1/2" and 2" straight flex that can be bent if required making it far more functional than rigid.
