Pressure Ratings Depend on the temperature
Principally, the working pressure ratings for the reinforced PVC hoses are based on the ambient temperature conditions. The maximum pressure a hose can withstand will be decreased as the temperature increases and the material becomes softer and more elastic. Fitting retention decreases at higher temperatures as the compression on the material declines.
Working pressure ratings can be affected significantly by the type of fitting used, the method of attachment, and the temperature to which the hose assembly is exposed in service. Repeated intermittent periods of exposure to elevated temperature can affect fitting retention and it is, therefore, very difficult to assign working pressure ratings at high temperatures.
The graph at left represents the relationship between temperature and pressure overall trend.



Cautionary Statement
The products offered by our distributors are in the nature of commodities and they are sold by our published specifications and not for particular purposes, uses or applications.
The purchasers or users of the products shall first determine their suitability for the intended purposes, uses or applications and they shall either conduct their own engineering studies or tests, or retain qualified engineers, consultants or testing laboratories and consult with them before determining the proper use for the intended purposes, uses or applications.
We do not recommend the products for any particular purpose, use or application, and the purchaser or user therefore shall assume full responsibility for the suitability, propriety, use and application of the products. The products may fail due to the use or conveyance of substances at elevated or lowered temperatures or at excessive pressures, the conveyance of abrasive, injurious, flammable, explosive or damaging substances.
Hose used in bent configurations will be subjected to increased abrasion. Hose clamps or couplings may loosen after initial installation and all sections of hose and tubing, including connections, couplings and clamps, should be inspected frequently, regularly and consistently, and should be replaced, adjusted or re-tightened for the avoidance of leakage, for the prevention of injuries or damages, and for general safety purposes. Except as indicated in its limited warranty, we; Zaisan; shall not be liable or responsible for direct or indirect injuries or damages caused by or attribute to the failure or malfunction of any products sold or distributed by it.
We recommend that the purchasers or users of the products frequently and consistently undertake inspections and protective measures with respect to the use and application of the products which should include the examination of cover condition of the hose, repair or replacement of sections showing cracking, blistering, separations, internal and external abrasions, leaking or slipped couplings or connections and make proper proof , tests.
