It might be a little late but FYI
Tigerflex is a lot more flexible than pvc at any temp below 120. Its what you see septic truck companies and Yellow Grease collectors like Darling, Brooks, RTI use.
The hose does start to retain some
memory in the cold after a few years but NOTHING like the clear suction pvc hose. I will never use that stuff for anything other than permanent install that needs visual of oil.
Move some 150 degree oil in it and most of the memory is gone.
Unless you find a local supplier cheaper, Varco Pumper Supply is the cheapest ive found hose and aluminum camlock fittings. I have come across a deal once in a while on camlocks on Amazon but its rare.
Varco's aluminum camlocks are cheaper than most places banjo or poly fittings.
EPDM Suction and Discharge Hose VARCO
Punch-Lok Hose Clamps - Small brass fittings - Couplings for industrial applications - International
They do carry a grease and oil compatible hose but its $$ and starts off at 1.5 inch
Varco /-WOR Series Oil-Resistant Corrugated PVC Suction Hose
Then there is this clear polyurethane and its $$$
Bulk OV Series Oil/Grease Suction Hose-Varco /
Handles most fuels and oils. Excellent resistance to gasoline, diesel, ethanol, blends (up to E30) and biodiesels (up to B100).
Only complain I have on camlocks is the edpm seals break down in 6-12 months so buy extras.
They do sell Viton versions but they are just as much or more than the fittings were the edpm seals are $0.20-0.80 each.
I did pickup some 1 inch Viton camlock seals at a great price on Amazon, 50 for $6.50 and free shipping.
