Grommets

BARBIERI RUBBER designs and manufactures rubber wire leads and rubber grommets in various shapes and sizes, for application to any opening for the passage of electrical wires, pipes or anything else that has to pass through a hole and needs to be protected from direct contact with the wall.

Description

Features

It is possible to produce grommets with special insulating and dielectric characteristics by replacing the carbon black in the formula with an insulating material such as silica.

Also, if suitably sized and designed, the grommets can be used to make containers with outgoing pipes or cables waterproof or suitable for underwater use.

The mix that is normally used combines elasticity with high resistance to mechanical and chemical aggression. This means that the waterproof seal will remain viable for many years, even in particularly severe environmental conditions, regardless of direct exposure to sunlight, or use in very cold or very hot climates.

Additional information

Application areas

In spite of the fact that a large number of materials are used in the production of grommets and are available on the market, the special characteristics of rubber grommets make them the best choice in terms of seal, protection, elasticity and long-term durability.

Rubber grommets in custom sizes are routinely installed in the sumps of septic tanks at the pipe outlets. The pipe lead seal membrane often has a minimum opening, and can be cut by the end user during installation, to make sure that the opening is the same size as the pipe to be used.
