Abstract: This disclosure provides an insulating member for covering a conduit in a clean room. The insulating member typically has a length and defines a cavity extending along the length. The cavity is sized and shaped to receive the conduit. The insulating member typically includes an innermost layer that may be a closed cell fluoropolymer foam and is disposed to contact the conduit. The insulating member also typically includes an outermost layer that is disposed on the innermost layer and that may be a second fluoropolymer.

Abstract: A sanitary cap for a sanitary end is provided. The sanitary cap includes a base which defines a central axis and has a peripheral edge. A flange extends from the peripheral edge along the central axis and a lip spaced from the base extends from the flange inwardly toward the central axis. The sanitary cap may include a crosslinked polyethylene foam or a breathable insert. A system including a sanitary hose and the sanitary cap is also provided. The sanitary hose includes a sanitary end. The sanitary cap is removably disposed on the sanitary end. The crosslinked polyethylene foam of the sanitary cap of the system is formed in the presence of nitrogen as a physical blowing agent, has a density of from 1 to 20 lb/ft3 when tested in accordance with BS ISO 7214 1998 Skin/Skin, and is a Class VI foam as defined by the United States Pharmacopeia.
