Moulded from low-density polyethylene (LDPE), Poly Plug temporary plugs provide a semi-flexible yet durable seal that maintains shape and grip even in extreme conditions. LDPE is chemically inert, UV-resistant, and impervious to moisture absorption, making Poly Plug ideal for both indoor and outdoor environments.

Designed for repeated use, Poly Plug plugs are a cost-effective solution for protecting ducts during installation, pull testing, or phased build programs.
