Do’s and Don’ts of
Hose Care and Use
Hose is a very vulnerable link in most process and transfer applications.
All hose will fail in time! It handles valuable and potentially dangerous
materials, and hose failures can be expensive in terms of lost product,
ruined equipment, spill clean up, and – most important personal
injuries.
For this reason, hose is carefully designed and built to do a specific job
safely and economically. Yet, unfortunately, the years of research and
development invested in hose construction can be canceled by
improper storage, misuse, and other abuse by the hose user,
warehousemen, and other work personnel.
Novaflex Marine & The Novaflex Group recommends careful
observation of the following points to improve service, safety and
economy for the hose you use.
Do – Use hose designed and recommended for the service intended.
Contact Novaflex Marine and our staff will assist you in the selection of
the best hose product for your requirements.
Do – Make sure hose is easily identifiable as to the type and use.
Where dangerous misuse can occur, use different fittings or end
connections.
Do – Make sure your Novaflex Marine Hose is the correct length for the
job intended. Remember to engineer for a possible -4% contraction to
+5% elongation at max working pressure on the hose assembly.
Do – Set up regular hose inspections before each use so that damaged
or worn hose assemblies can be replaced.
Do – Attach hose using proper elbows and nipples, so that its operation
(including its own weight and heavy end connections) will not cause it to
bend sharply at the coupling. Support hose ends with heavy couplings
attached.
Do – Avoid placing hose in applications in which vibration, rubbing or
damage from other external materials may occur. It is easy to install
protective covers on hose.
Do – Check manufacturer’s chemical resistant charts to insure the hose
will transfer the products before it is put in the hose.
Do – Store hose in a cool, dry, dark and clean place.
Do – Only use hose that is rated for below the water line applications,
by the manufacture .
Do – Wear safety clothing, gloves, boots, hard hat and eye protection
when using a hose.

3. Carefully examine a length of the
hose (18" in length adjacent to
where the hose is attached) for
any damage such as kinks, soft
spots, cover cracks, or permanent
deformation of the hose from its
original form.

4. Check hose attachment for any
slippage which is evidenced by
misalignment of the coupling or
scored/exposed areas on the hose
cover next to the coupling which
indicates movement of the hose.
