Basics of SS Braided Hose Pressure Rating
The pressure rating of an SS braided hose refers to the maximum pressure it can safely handle. This rating is not random—it ties directly to the hose’s design and materials. SS (stainless steel) braids act as a reinforcement layer, boosting the hose’s pressure resistance far beyond non-braided options. Most SS braided hoses have a pressure rating ranging from 300 PSI to 5,000 PSI, but this varies by size and application. Always check the manufacturer’s label for the exact rating of your SS braided hose.
Key Factors That Shape SS Braided Hose Pressure Rating
Several factors influence an SS braided hose’s pressure rating. First, the thickness of the stainless steel braid matters. Because thicker braids with more strands handle higher pressure. Second, the inner tube material plays a role: rubber or PTFE inner tubes have different pressure limits, even with the same SS braid. Third, hose size affects rating. Smaller SS braided hoses often support higher pressure than larger ones. For example, a 1/4 inch SS braided hose might rate 3,000 PSI, while a 1-inch model rates 1,500 PSI.
Temperature’s Impact on SS Braided Hose Pressure Rating
Temperature changes alter an SS braided hose’s pressure capacity. High temperatures soften inner tubes and weaken stainless steel braids, lowering the safe pressure rating. Low temperatures can make some inner materials brittle, also reducing pressure tolerance. Manufacturers provide “temperature-pressure charts” for SS braided hoses—use these to adjust pressure limits in extreme conditions. For instance, an SS braided hose rated 2,000 PSI at 70°F might only handle 1,200 PSI at 300°F.
Why Following SS Braided Hose Pressure Ratings Matters
Ignoring pressure ratings leads to SS braided hose failure. Exceeding the rating can cause the inner tube to burst or the SS braid to unravel, leading to leaks or even dangerous bursts. This risks equipment damage and safety hazards, especially in industrial or hydraulic applications. Always match your SS braided hose’s rating to the system’s maximum pressure. Regularly inspect hoses for wear—aging can lower effective pressure capacity, even if the label stays the same.
