Also known as Buna-N, nitrile rubber is highly oil-resistant. This makes it the first choice for grommets when exposure to oil is a possibility. Electrically, it is a semiconductor (a substance with electrical conductivity halfway between an insulator and a metal) and is also antistatic.Additionally, if the grommets are made from NBR nitrile rubber, there is a mechanical industry standard that indicates a shelf life of 4-5 years. Fluorocarbon Rubber Clark Rubber grommets are made from long-lasting natural rubber. It provides better heat insulation than other kinds of grommets. Plus, rubber grommets will often ensure longer-lasting protection for your wires and furniture than metal or plastic equivalents.

This resilient material is resistant to heat, flame, ozone corrosion and weather, making it a good choice for use outdoors and in areas of fire risk. SiliconeAlso known as blind rubber grommets, closed grommets provide air-tight seals when applied, and can be a good choice for sealing holes not currently in use to prevent the build-up of dust. Rubber blanking plugs are used to seal holes and are designed to hold and control pressure coming from above or below, making them a good grommet choice for high-pressure UK devices and tubing. Rubber grommets also take up less space, leaving a flush and attractive finish. Different grommets for different jobs Unlike similarly shaped round grommets, blind rubber grommets have no central hole. They are widely used by the UK electronics industry. Some feature a small hole into which a wire can be inserted for a firm hold. These are called diaphragm grommets. Open Rubber Grommets

Also known as FKM or Viton, fluorocarbon rubber is a particularly stable rubber effective that can withstand high temperatures and strongly acid or alkali environments. Neoprene Rubber grommets are pieces of rubber that protect or cover an edge and protect cables or wires from sharp corners or edges. They are commonly used for electrical installations and for home improvement. Most grommets are made from rubber, but plastic grommets are available in the UK and elsewhere, along with models made from other materials, including:When installing an electrical connection, use a wiring grommet to make sure the wires are protected against walls and sharp objects. This will prevent damage to the wiring from the walls and sharp objects. Then, to seal up any holes that you’ve drilled in the process, use a blind grommet. Rubber grommets are available in several different types. Here are the principal ones: Rubber Blanking Plugs

And we have them in all the different shapes and sizes you need to cover up holes and sharp edges. Don’t get caught out down the line --- grab some grommets today. Long lasting rubber grommets This offers good tensile strength and resistance to strain and tears, along with strong electrical insulation. Nitrile Rubber Open rubber grommets are the most basic design, featuring a central hole. They are used to protect cables and pipes when they pass through holes in metal plating.
