How to identify plastic materials
Cracks in rubber hoses happen often, and two main issues cause them. First, rubber hoses oxidize after long-term use. Second, working pressure may exceed the hose’s actual capacity. Most broken hoses needing repair fail due to aging. But Orientflex doesn’t recommend repairing cracked hoses. Every hose has a set service life—cracks usually mean that life has expired. Even after repair, the flexible rubber tubing faces a high risk of breaking again. This makes accidents more likely. Continuing to use a repaired high-pressure rubber hose thus creates serious safety risks.
The Bonding Method for High Pressure Rubber Hose Repair
That said, a bonding method works for temporary repairs on high-pressure hoses with pressure between 2.5–8MPa. Start by wiping the area around the rupture clean. Then apply oxygen resin glue, 801 glue, or “502” glue—cover an area 2–3 times longer than the crack. Next, wrap the glued area with tape or canvas strips, adding 4–5 layers. Coat each layer with glue as you go. Tie the ends of the wrapped tape or canvas into tight knots. Wait 15–20 minutes for the repair to solidify before using the hose.
This is one common way to repair high-pressure rubber hoses. For more tips, follow Orientflex. As a professional hose manufacturer with over 15 years of experience, we’re here to help. Contact us now to learn more about hoses.
