Additional Info:

Provide reliable, chemically resistant sealing with solid‑top screw caps designed for general storage and laboratory applications.

97015-SP2 caps feature a durable knurled polypropylene design for improved grip and consistent handling. The solid cap incorporates a white silicone rubber / red PTFE liner, offering a flexible yet secure sealing interface ideal for storage vials and bottles without the need for septa penetration.

The liner is 1.3 mm thick with a 45° Shore A hardness, providing a softer, more conformable seal compared to higher durometer materials. The PTFE layer ensures excellent chemical resistance and inertness, while the silicone backing enhances compression and resealing performance. These caps are well suited for routine storage applications where dependable sealing and compatibility with a wide range of chemicals are required.
