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.

G941HT… SPA FLEX
Construction: Cream coloured, flexible PVC, embedded with a
rigid PVC helix.
Interior: Flexible PVC, smooth for unrestricted flow.
Exterior: Smooth, cream coloured, weather resistant PVC.
Temperature Range: -20°C (- 4°F) to 65°C (150°F).
Note: Please use a PVC-to-Flex cement for attaching PVC fittings
to hose. Suitable cements include:
– Permalite Plastic #VIC 504
– Uniflex Pipe Cement
– United Elchen 6700 Series PVC to Flex
– Weld-On #795 PVC/Flex.

And these are the specs I asked for

size 11/2" model # G941HT-150 I.D. 1.65" O.D. 1.90"

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
