B757 Lavatory Hose (FAA PMA Approved):
This upgraded FAA PMA approved lav hose design is in response to the original OEM design's field failures. Co-Op's improved hose assembly features an elbow with a wall thickness that is double that of the original design. This stainless steel elbow guards against the sharp tools used to dislodge ice buildup. The silicone hose material provides better insulation and flexibility, while offering the added strength and durability of Kevlar®, Stainless Steel, and Nomex® overbraids. This combination of materials and fittings assures a burst pressure rating of 250 psi.
This design is considered form, fit and functionally interchangeable with its predecessor. In comparison of price, you will find our design offers a significant cost savings.
Our kick-off operator has had the upgraded service hose in service for a number of years with no failures and excellent operational results.
