Safety Instructions

Following are SPIR STAR®'s lists of Do's & Don'ts for the proper safety practices when using high-pressure hose.

Care and Use of High Pressure Hose


  • Treat high pressure hose with extreme caution. SPIR STAR® hoses are wire reinforced hoses with a thermoplastic inner core and should be treated with the same care as a high-pressure containment vessel.
  • When using hoses for water-jetting, read and understand Recommended practices for the Use of Manually Operated High-Pressure Water Jet Equipment (Water Jet Technology Association [+1/314-241-1445, www.wjta.org])
  • Always visually inspect for frayed, damaged or wear spots before using.
  • Check the hose end connections and threads for wear, rust, cracks, mechanical abuse or other deterioration that could produce a dangerous projectile.
  • Know the working pressures and burst pressures of all hoses before using them.
  • Always use clean, filtered water to prolong hose life. Do not use water that is high in sulphur because sulphur may attack stainless steel.
  • Always clean, drain and coil hoses after use. Soap and water usually provide an excellent cleaning agent.
  • Always wear protective gloves, eyewear and garments when handling high pressure hose and water jet lances.


  • Don’t use a hose with cuts or wire showing through the outer cover.
  • Don’t use a hose that has been kinked.
  • Don’t use a hose that has bubbles or blisters in the outer cover.
  • Don’t exceed the bend radius and pressure rating for each hose.
  • Don’t run over or crush the hose with heavy vehicles.
  • Don’t use a hose with corroded or leaking end connections. Take it out of service immediately.
  • Don’t use hoses that have been exposed to chemical attack or over temperature.
  • Avoid using dirty water or water with sulphur compounds in it. Tests have documented that hoses fail more rapidly when using water sources from chemical plants and refineries.
  • Don’t bend the hose over scaffolding or pull heavy equipment with the hose.
  • Don’t let the hose support its own weight off towers or buildings.
  • Don’t expect water jetting or hydraulic hose to last forever.
  • Don’t mechanically rotate the hose without a slipclutch device
