Flanged Caps

Not all cap uses are meant to be permanent. In fact, there are plenty of instances where you’re going to want to remove them. This is where Polymer Molding’s FC series flange caps can be of great use to you. PMI’s low density polyethene flanged caps are designed to fit standard threaded fittings or smooth cylindrical tubing. It has a flanged top surface for ease of removal. This way, you can get a better grip on the material and remove it without needing special tools or additional leverage. Find the perfect FC series flange cap for your needs here.

Flange seal caps are commonly used in applications where temporary sealing or protection is necessary during finishing, masking, or transport. These flanged plastic caps are well-suited for covering exposed threads, ports, and fittings that need protection from debris or damage. For larger openings, a pipe flange cap provides dependable coverage while maintaining flexibility for repeated use. With secure fitment and straightforward removal, these flanged caps support both protection and productivity in industrial settings.
