this is the information on the product I bought as it is on the bottom of the spec sheet

				Spa Flex Hose is designed to replace PVC pipe on Hot Tubs 
and Spas. G941HT has the IAPMO plumbing safety approval 
and uses the same external glue-on schedule 40 fittings 
as rigid pipe but is much easier to install. Hose will bend 
without heating and will follow the curves and corners on 
a spa without having to use elbows. Spa Flex is ordered 
by nominal pipe size.

 And by measuring the ID and OD of what I bought I think they gave me the wrong size as it measures to the same specs as the 11/4" spaflex
Back to the store tomorrow to replace the size
