— SE400 hose: A hose sleeve fits around the entire length of the hose

— Gloves: Chemically impermeable gloves are fastened to the rigid sleeve rings with an airtight seal. The gloves are designed to be worn inside regular working gloves or rubber, leather or other materials. NOTE: The supplied gloves are impermeable and impregnable, but are not designed for mechanical wear and tear. Heavy-duty outer gloves of butyl rubber, leather or similar must be worn over the inner gloves.
