With long hose lengths and large quantity requirements there is opportunity for cost savings for shipping and raw material cost. With increased pressures to save on freight and rising price on rubber hydraulic hose, smart purchasing agents and engineers will need to look to lighter and more flexible materials to substitute for increased profits and flexiblility.

If you consider bend radius, Dyna Flex Inc. 711 series thermoplastic is more flexible in 1/4 inch inner diameter and 3/8 inch inner diameter and is the same for 1/2 inch inner diameter. Thermoplastic hose minimum bend radius is less than 1/2 that of standard push on hose for 1/4in inner diameter. Dyna Flex Inc. 711-04 SAE100R7 1/4 inch inner diameter hose has a bend radius of 1-1/4inches. Comparable 250psi push-on hose has a 3 inch inner diameter. As an extra benefit Dyna Flex Inc. has a 1/8 inch inner diameter hose with a 1/2 inch minimum bend radius in conductive ( Dyna Flex Series 701-02) and non-conductive (Flex 7110-02) configurations.

If you consider weight, Dyna Flex Inc. 711 series thermoplastic is at least 14% lighter in 1/4 inch inner diameter and 3/8 inch inner diameter and is the same for 1/2 inch inner diameter. As an extra benefit Dyna Flex Inc. hose can be made in twin and in conductive ( Dyna Flex Series 711) and non-conductive (Dyna Flex Inc. 7110) configurations.

Disadvantages of 711 series hose would be hose ends would need to be crimped as opposed to being pushed in by hand. It would be also easier to uncoil and coil push-on hose.

If you have an application which has lengths requirements of 50ft and longer and hose crimping is not an issue, Dyna Flex Inc. Series 711 hose may be a viable alternative. Couplings can be supplied in carbon steel, stainless steel, and brass. Please contact us for specification sheets.
