Is $40 for 3 feet of 3" silicone hose too cheap?

I have been looking for a stick of 3" silicone hose to have on hand for emergencies.  Napa wanted $60 to $69 a foot for the hose in three foot chunks only.  I've found the hose for around $30 a foot online.

But, Ryder Fleet Products has Purosil Burke 3" silicone hose in a three foot chunk for $39.21.  That seems pretty cheap compared to all the others. 

Is there something wrong with this hose?

Belfert, Purosil is a great hose it not 100% silicone it has a fluorocarbon linng to prevent the cold weather leaks associated with  100% silicone hose.       good luck
