The special plastic material from which Cobovac hose is made resistant to most acids and alkalies. There is no metal used in the construction and therefore no metal to corrode.
The unique ball and socket construction, plus a welded composite structure, makes this hose virtually indestructible under normal conditions.
The smooth bore of Cobovac hose is important because it keeps frictional losses to a minimum. Its abutment construction keeps it from reducing in length under vacuum.
Jump on it - twist it - slam it in a door - run over it with a truck - have an elephant walk on it - and it comes right back to shape as though nothing had happened. An important feature for many applications.
Cobovac hose is made by a continuous process (patent pending) so can be supplied in virtually any length required. Continuous lengths up to 75 feet are no problem at all.
Modern design - uniform construction - smooth plastic material and two-tone color give Cobovac hose unsurpassed appearance. Two tone (silver on black) is the standard color - but you can have any color combination you want on special order.
Suppose you want to shorten a piece of Cobovac hose. You don't need a hacksaw - wire clippers or an ax. Just unscrew the end fitting - cut the hose off with a pocket knife and screw the end fitting back on the shortened hose. It's as simple as that.
Cobovac hose is so light that it will float in water even when filled with water - a remarkable achievement (an original by Cobovac) made possible by eliminating metal from the construction - using special plastic material with a specific gravity less that 1 - and by unique construction. (patent pending.)
