Product Overview

The all-aluminium expanding plug has an aluminium alloy body; during installation the expansion structure makes the body expand radially and press tightly against the hole wall to seal, with a sealing level of up to IP68. Its aluminium body is compatible with aluminium substrates to help lower galvanic-corrosion risk (per actual design); suited to one-time permanent plugging of process and inspection holes, long-term maintenance-free with no repeated disassembly.
