GROMMETS

 

rubber wire leads and rubber grommets

BARBIERI RUBBER designs and manufactures rubber wire leads and rubber grommets both with a symmetrical and WS design, for application to any opening for the passage of electrical wires, pipes or anything else that has to pass through a hole and heeds to be protected from direct contact with the wall.

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

 

Also, if suitably sized and designed, the grommets can be used to render containers of any type that involve 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 seal and protection are ensured for many years, even in particularly severe environmental conditions, regardless of whether they are exposed to direct sunlight, or installed on equipment that is used in geographical areas with a very cold or very hot climate.

rubber grommets in various colors and dimensions

 

In spite of the fact that a large number of materials suited to the production of grommets are available on the market, only the properties of rubber will give the same results in terms of seal, protection, elasticity and long-term retention of the same characteristics.

rubber grommets of special sizes

 

 

Rubber grommets of special sizes are also 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 on installation in the septic tank, so that the opening is the same size as the pipe to be used.

Suggested materials:

SBR
Styrene-butadiene rubber
NBR Nitrile rubber
EPDM Ethylene-pylene terpolymer
EPDM Die Insulating rubber

(Standard = EPDM)
