An explanation For Hydraline SB vs Smoothbore
Hydraline SB Hose is the same as ordinary Smoothbore hose, except it has a
bigger bore (to fit hydraulic fittings) and it is usually "Medium Wall" (MW),
where Smoothbore is only available in "Standard Wall" (SW) or "Heavy Wall"
(HW). Hydraulic SB is referred to by different titles by different
customers, although it is all the same thing. It is usually
referred to as "Medium Wall" (MW) Hose, sometimes as "Big Bore" (BB) Hose and
sometimes as "Dash Size" Hose.
