mike2016 Posted October 4 Posted October 4 I've a few 4" pipes for running services outside and now I'm sealing up I want to tackle this area before my final air tightness test. I was looking at Wiska Gel or similar, can any solicone be used or is there a safer type for electrical cables - I've a 4" plug sealing the pipe but the cable holes have gaps I want to gel up if possible. Thanks.
