Hose Assembly Do's & Don'ts
- Feb 05, 2018 -
When making or installing a hose assembly...
Never use a component that appears to be dirty, cracked, blistered, kinked, or non-conformant in any other regard
Never crimp or swage a Parker hose or fitting with anything except the listed swage or crimping machine and dies
Never re-use a field-attachable fitting that has blown off or pulled off a hose
Never re-use a permanent fitting (whether crimped or swaged) or any part thereof
Never assemble fittings to any hose that was previously used in service when the hose was the cause of the original failure
Never use a section of hose that has been kinked during unpacking or installation
Never install a hose in such a way that it will be stretched, twisted, or in any other way re-oriented from its natural lay during use
Never apply a twisting or torquing action to a hose when tightening fittings, or allow twisting or torquing to occur during installation or when the assembly is in use
Never allow tensile loads, side loads, kinking, flattening, abrasion, thread damage, or sealing surface damage to impede the proper installation
Never complete an installation without eliminating all air entrapment and pressurizing the system to a pressure equal to or less than the maximum working pressure of the assembly’s weakest link
Never forget that fluids coming into contact with hot surfaces, open flames, or sparks could ignite an explosion
Ask Yourself these Questions.....
Have you left sufficient slack?
Are there any twists in the hose?
Are any hoses rubbing against each other or against other components?
Have you allowed for system vibration?
Is the hose protected against kinking?
Is the hose protected against heat, sparks, or open flames?
Is the hose protected against abrasion or chafing?
