Hose protectors keep your hose rubber jacket from pulling loose from the crimped metal fitting. Once the hose jacket has separated and exposes the breaded hose inner liner you will start to have a hose leaks. Hose protectors that are not vented or do not have a ribbed interior surface retain water and promote corrosion of hose fittings and hose rot. Protect your hose from these problems with this vented hose protector. Use one on every hose attached to your first-stage regulator to prolong the life of all your life support fittings. Hose Protector is available in black color and is made from durable vinyl. The Hose Protector is vented for easy water drainage and rapped drying.
