SMSKu-E-H0 is a plastic push-fit coupling made of special plastic, in grey (RAL 7035), non-flame propagating, zero halogen.
This push-fit coupling is used to connect FPKu-EM-F-LS0H Low Smoke and FPKu-EM-F-H0 straight length plastic conduits and all zero halogen corrugated conduits.

An advantage is that it does not contain halogens that prevents the formation of dangerous toxic and corrosive gases.
