Flexible grommets to suit your application

HellermannTyton cable grommets

Sharp edges, constant mechanical stress, chemicals or environmental influences: There are many factors that can damage cables.Cable grommetshelp tominimise these risksand toprotect the cabling.

For example, if cables have to be routed through small round holes,snap in cable grommetshelp prevent abrasion. In the case of larger, or unshaped cut-outs withsharp edgesor straight edges, the use of so-calledgrommet stripsis a good choice.

Another form of cable grommets are those that are inserted into cable ends. Thesegrommets relieve cables from strain. Other cable entry sleevesprotect the cable from bending or kinking– so calledanti-kink grommets. And some cable grommets combine both bend protection and strain relief in one.

No matter which cable protection is the best for your specific application, we have the right cable grommet solution for you.

Snap in cable grommets

Open grommets to protect against chafing

Snap in cable grommet for punched or drilled metal sheets

Wherever cables have to pass through holes, the use ofsnap in cable grommetsis a good choice.

These open grommetsprotect the cables and wires optimally from abrasion on sharp edges.

Further benefits:

  • Additional strain relief
  • Flexible and easy to process
  • High chemical and environmental resistance
Snap in cable grommet: protects cables from sharp edges

Cable pass through grommets for edge protection are available in the colorsgrayandblackfor edges with wall thickness from 0.8 to 6.0 mm.

They are available in bothcircularandovalformats. The latter are also calledoblong grommets, suitable for flat cables or ribbon cables.

They are made of PVC orflame retardant PVC-FR.

Grommet strips for sharp-edged panel edges and cut-out sections

TheEdgeGuard flexible grommetprovidesoptimum protection for cableswhen routed along sharp-edged areas.

Thanks tosoft, flexible PVC, this cable management grommet iseasy to applyandfits the edge perfectly.

In addition to the cable protection aspect, EdgeGuard is also adesign solutionfor attractively covering edges, available in three different variants:

Slotted grommet edging for sharp cutouts

Flexiform grommet strip for cut-out sections

TheFlexiform edge protectorfor cables is often used for sheet metal cut-outs. However, thisflexible grommetalso ensuressafe and material-friendly cable routingat any otherhard-edged cut-outs, e.g. in chassis or device construction.

The advantages at a glance:

  • Tight-fitting, slotted moulded rail
  • Very flexible, bendable material (PTFE)
  • Easy and safe installation without adhesive
  • Excellent protection at high temperatures

Flexiform is available in 3 different material classes:

  • G51P: made of PE, -30°C / +80°C, standard abrasion resistance
  • G51N: made of PA6, -60°C / + 95°C, high abrasion resistance
  • G51T: made of PTFE, -60°C / + 260°C, high temperature + chemical resistance

Cable grommets for strain relief and bend protection

Cable entry sleeves

Cable entry sleeve for bend protection

Cable grommets for strain reliefprotect the wire or electrical connection from damage when pulled.

Benefits at a glance:

  • Flexible and simple to install
  • Ensure high tensile strength
  • Very resistant to chemicals and environmental influences

Additionally, there areanti-kink grommets, used, for example, atoutletsasmechanical protectionfor cables and wires.

Some grommetseven combine both properties: they relieve the cable and protect it from kinking.

Frequently Asked Questions

What is the purpose of a cable grommet?

Strain protection grommets

A cable grommet typically is around edged ringinserted into a panel holeto protect pass through cablesfromchafing and abrasionas well as fromenvironmental impactsor simply assuring afirm gripof the wire or cable.

Sleeved cable grommetsalso avoid the cable getting kinkedor are used to ensure proper strain relief.

How to install wire grommets?

Edge protection grommet for punched or drilled metal sheets

An open cable grommet issimply pushed through the panel hole by handuntil it snaps firmly in place.

Theflexible materialallows the grommet to be squeezed for ease of installation.

After installation, the edged designsecures the grommet from falling out.


How to choose the right open cable grommet

Choosing the right grommet is requiring3 basic dimensions. Your cable diameter, the diameter of the panel hole and the panel thickness.

FHdimension = panel hole size

H2dimension = panel thickness

Ddimension = the hole size of the cable grommet, depending on the diameter of the cable to be passed through it

Two complementary parameters are theHdimension (height) and theODdimension (outer diameter), which describe the overall size of the cable grommet.
