unique in providing immediate, expert applications assistance, and in having the high-pressure
spiral hose you need now, available now – in stock.  Our best-selling products in this group are:

Parker 721 Hydraulic Hose – ideal for routing in tight spaces; meets SAE 100R12,
ISO 3862-1 and EN 856 Type R12 specifications. Its one-half SAE 100R12 minimum bend
radius lets users complete installations in tight spaces, with less hose length required. 

This high-pressure spiral hose has a 4000 psi working pressure for 3/8'' ID through 1'' ID sizes;
3000 psi in the 1-1/4'' ID; and 2500 psi in the 1-1/2'' and 2'' IDs.  It is compatible with petroleum-
based hydraulic fluids and lubricating oils, emulsions and water/ glycol hydraulic fluids.

Construction for 721 high-pressure spiral hose is a neoprene synthetic rubber inner tube
surrounded by four spiral layers of high-tensile steel wire reinforcement. An MSHA-accepted
black synthetic rubber cover provides oil and weather resistance;  a gray Mylar tape lay-line
makes 721 hose easily identifiable.

For ultimate leak protection, Valley recommends using 721 high-pressure spiral hose with
a Parker Parkrimp 71 Series or BW Series fittings. The no-skive design of 721 hose allows it
to be crimped without removing the hose cover.
