Nalgene® Pour Spout Closures
Nalgene® pour spout screw cap closures are made of polypropylene with a polyethylene insert. Pour spout screw caps can be used for all Nalgene® bottles with a 38-430 (38mm) neck finish. This pour spout is lighter in weight than glass, and protects against leakage, breakage, and contamination. It offers a safer alternative than glass, without sacrificing accuracy.
