Every 3M Motor Lead Pigtail Splice Kit comes complete with tubes of silicone grease, mastic sealing strips and pigtail lug covers. The mastic strips contained in the kit allow you to seal moisture while the slip-on lug cover is made of a durable EPDM rubber that holds up under pressure. When lugs are crimped onto cables and bolted together in a pigtail configuration, this kit is then used to seal and insulate the lugs. This product is CSA Certified and RoHS 2011/65/EU Compliant.
