Thermoplastic hoses - polyester
Internal layer: Polyester
Reinforcement: Polyester braid
External layer: Pinpricked polyurethane
Lightweight, flexible hose designed for hydraulic oil installations, gases, air, fuels, water-based
fluids.
Use Z type fittings (IT-61).
Hoses for medium and high pressure made of thermoplastic polymers (such as polyester, polyamide, polyurethane) reinforced by max 2 layers of steel or textile braids. Most types manufactured to certain standards i.e.: SAE J517 (for hoses SAE 100R7 and SAE 100R8), DIN 24951, ISO 3949 and PN-EN 855. Those standards in details describe two types of hoses: with double textile braid (R7) and double aramid braid (R8). Thermoplastic hoses widely used in hydraulics, airless paint spray, air and compressed gases, chemicals and water cleaning.
Thermoplastic hose characteristics:
very low weight (even up to 60% lighter compared to rubber hose),
compact structure (small external diameter in proportion to the internal one),
small bend radius,
good chemical resistance of an internal layer to hydraulic oil and chemicals,
very smooth internal layer surface that reduces the loss of flow rate,
resistance to ageing, ozone and ultraviolet radiation.
resistance to abrasion of external layer (polyurethane).
