APM HEXSEALS ® and E-SEELS ® environmental sealing boots provide cost-effective, long-term protection for switches and potentiometers, which can resist water, oil, dust, dirt, salt spray, fungus and other environmental contaminants.
APM HEXSEAL provides a range of sealing boots designed to protect switches and potentiometers from water, oil, dust, salt spray, fungus and other harsh contaminants. The catalog explains how the high‑tear‑strength silicone rubber, integral sealing rib, and optional EMI/RFI shield keep panel‑mounted components reliable in demanding environments.
Three performance families are offered—Military‑Qualified, Industrial‑Grade, and Commercial‑Consumer—each with defined temperature ranges, material options, and certification levels. Detailed specifications, ordering information, and step‑by‑step installation instructions are included for both threaded and non‑threaded designs.
