1. Inspect the Steel Wire Layer for Strength
The steel wire layer is the core of a PVC steel wire hose—it determines pressure resistance and anti-kinking ability. First, check if the steel wire is evenly embedded in the PVC layer. A loose or uneven steel wire layer will make the hose burst easily under pressure. Then, confirm the steel wire’s thickness; thicker steel wires mean stronger load-bearing capacity. For example, a PVC steel wire hose with 1.2mm steel wires works better for industrial water transfer than one with 0.8mm wires. Avoid hoses with rusty steel wires, as they will corrode quickly and shorten the hose’s life.
2. Check the PVC Coating for Durability
The outer PVC coating of a PVC steel wire hose protects it from wear, sunlight, and chemicals. First, press the PVC surface gently— it should feel firm, not soft or sticky. A soft coating will crack easily when exposed to low temperatures. Then, test its water resistance: wipe the hose with water and check if the coating absorbs moisture. A good PVC steel wire hose has a waterproof coating that keeps water from seeping into the steel wire layer. Also, choose hoses with UV-resistant PVC if you’ll use them outdoors, as this prevents fading and aging.
3. Verify Compatibility with Your Usage Scenario
Different PVC steel wire hoses fit different needs. First, match the hose’s diameter to your task: a 1-inch PVC steel wire hose suits home car washing, while a 2-inch one is better for construction site drainage. Then, check the connection type—most use threaded or quick-connect fittings. Ensure the fittings match your faucets or pumps tightly; loose connections cause leaks. Finally, confirm the temperature range. If you’ll use the hose for hot water, pick one that resists up to 60°C. As regular hoses may melt at high temperatures.
