Bushings –
Reliable cable protection
for each application.
Cable protection grommets
and safe execution.
Isolation grommets and cable entry grommets are among the most important components in cable management. They reliably protect cables from abrasion, sharp edges, and mechanical stress. At the same time, they ensure clean and secure cable entry through housings, sheet metal, or machine components.
At Püplichhuisen, you can find a wide range of rubber and silicone grommets, cable entry grommets in various designs, as well as cable protection, bundling and labelling grommets – for applications in industry, automotive engineering, electrical engineering and mechanical engineering.

Advantages and benefits of
Isolation sleeves and feed-through sleeves.
- Cable protection Prevent damage from edges, heat or friction
- Durable Durable materials such as rubber, silicone, or plastic
- Diverse Available for single cables, cable bundles, or special applications
- Flexible Available in numerous designs and sizes
- Safety Increase operational safety and extend the service life of pipelines
Technical specifications
and materials.
Cable glands and cable entries differ not only in their design but also in their material properties:
- Rubber Grommets flexible, oil- and weather-resistant, Shore hardness between 40–70, temperature range mostly from –30 °C to +80 °C
- Silicone grommets Extremely temperature-resistant (up to +200 °C), ageing and UV stable, still elastic even at –50 °C
- Plastic grommets: Cost-effective alternative, lightweight, available in various colours for identification
- IP ratings Certain nozzle designs meet IP protection classes (e.g. IP54–IP67), which guarantee protection against dust and moisture.
This makes grommets not just simple cable glands, but also safety-relevant components in electrical installations.
Variations of isolation grommets
and execution nozzles.
What are they?
Rubber boots.
Classic rubber grommets are flexible, durable and easy to install.
They provide robust protection for cable entries in sheet metal or plastic housings and are universally applicable in electrical engineering and automotive technology.

Silicone nozzles.
Silicone hoses are particularly resistant to temperature and ageing.
They are suitable for environments with high thermal loads, such as engine or machine rooms, and remain elastic even in the cold.

Conduit glands
different designs.
Püplichhuisen offers cable glands in a wide range of shapes and sizes – from simple standard glands and blind glands to multi-part designs for cable harnesses.
They enable a precise cable entry and prevent dust or moisture from entering.

Cable grommets.
Cable grommets are reinforced variants that reliably protect cables from abrasion, vibrations, and heavy mechanical stress.
They are frequently used in vehicles, machinery and electrical installations.

Labelling ferrules.
Marking ferrules enable the unique marking of lines or cable bundles.
They simplify maintenance, repair, and documentation, and are available in various colours or erasable variants.

Application areas of
Isolation sleeves and feed-through sleeves.
Cable glands are used in numerous industries – wherever cables need to be safely guided and protected:
- Electrical cabinet construction for clean and safe cable entries through sheet metal enclosures
- The automotive industry Protection against vibrations, heat, and sharp edges in the engine compartment
- Mechanical Engineering secure routing of wiring harnesses in complex systems
- Electrical Installation Cable protection in buildings, walls and junction boxes
- Aviation and Rail Silicone or specialised grommets for extreme temperatures and continuous stress

FAQ: Frequently Asked Questions
on insulation sleeves and
Feed-through sleeves.
What is the difference between rubber and silicone grommets?
Rubber grommets are versatile and cost-effective, whilst silicone grommets offer greater resistance to high temperatures and ageing – making them ideal for demanding environments.
Are bushings waterproof?
Standard feed-through grommets are not watertight. Special versions with sealing lips or blind grommets are used to protect against moisture.
When is it advisable to use cable protection grommets?
Whenever lines are subjected to heavy mechanical stress, such as from vibrations, movement, or contact with sharp edges.
What are the advantages of cable grommets?
They ensure order, reduce space requirements and protect multiple cables at the same time. This is particularly practical in control cabinets or cable harnesses.
How do labelling sleeves help in everyday life?
They enable quick identification of cables, simplify maintenance and documentation, and reduce errors during repairs.
Can grommets be retrofitted?
Yes, many seals can also be retrofitted using flexible material. For very tight installation situations, slotted or two-part variants are often used.
How do I find the right size for a cable gland?
The size depends on the cable diameter and the drill hole diameter. Manufacturer specifications usually contain matching dimension tables.
