Sonda Fuel and Oil hoses are manufactured from multi-layers of polypropylene fabric and film with a weatherproof and abrasion resistant outer cover. The hose layers are held and tensioned between internal and external wire helices. Computer-aided design has resulted in exceptional strength-to-weight ratios and extreme flexibility, giving the hoses excellent handling characteristics. This ensures ready operator acceptance and encourages good usage practice. All hoses get the approval of international standards including EN13765, BS 3492(1987)AX + BX and BS5842(1980), and can be supplied with factory-fitted end connections to the customer’s requirements.
