Open Grommets
Features an open central hole allowing cables, wires, hoses, or fluid lines to pass cleanly through a panel cutout without edge abrasion.
Rubber Grommets Manufacturers in India
Thermoplastic elastomer (TPE) rubber grommets are intended to be applied and cover the metal, plastic, or fabric surfaces to insulate them. These industrial grommets ensure the safety of cables, wires and tubes by preventing damage as well as minimize friction and wear. TPE is a composite of rubber and plastic, possessing great ability to resist temperature, chemicals and harsh environment. Being a reputable manufacturer of rubber grommets, and one of the best grommet manufacturers, we provide high quality rubber grommet solutions, which are used in numerous applications in automotive, electrical and industrial applications. Our rubber grommets are simple to fit, cushion and have good sealant performance.

Types of Rubber Grommets We Manufacture
We manufacture a comprehensive range of grommet geometries engineered for cable strain relief, edge protection, panel sealing, and isolation:
Closed / Blind Grommets
Complete solid-center profile with no central hole; used to blank off unused panel openings, keeping out dust, dirt, and liquid.
Semi-Blind Grommets
Formed with a thin, tearable central web membrane that can be pierced on-site when wiring is routed, functioning as both a plug and an open grommet.
Grommet Edging / Strips
Continuous profile strips designed to fit along long, sharp, or irregular sheet metal edges where press-fit individual grommets cannot be seated.
Tapered Grommets
Features a sloped external body profile that accommodates varying panel thicknesses while maintaining a secure, press-fit seal.
Stepped Grommets
Designed with multi-diameter tiered cut lines, allowing operators to trim the grommet to the exact cable outer diameter on the assembly line.
Cable & Wire Grommets
Engineered with internal ribbing for enhanced strain relief and pull-out resistance at high-vibration electrical entry points.
Vibration Mount Grommets
Formed from soft, high-dampening elastomeric compounds to isolate delicate electrical instruments and motors from structural vibration.
Custom Shape Grommets
Non-circular profiles including oval, square, rectangular, and D-shaped configurations precision-moulded to your exact enclosure cutouts.

Frequently Asked Questions
What are polyurethane grommets and their advantages?
Polyurethane grommets are durable and flexible, offering excellent resistance to wear, chemicals, and temperature, making them ideal for heavy-duty applications.
Can I get a custom rubber grommet for specific applications?
Yes, a custom rubber grommet can be designed in different sizes, shapes, and materials to meet specific industrial or automotive requirements.
What are rubber grommets made from?
They are typically made from natural rubber, synthetic rubber, or thermoplastic materials depending on the application.
How to choose the right grommet suppliers for industrial needs?
Choose reliable grommet suppliers based on quality, experience, customization options, and ability to meet industrial standards.
Are custom rubber grommets suitable for automotive applications?
Yes, a custom rubber grommet is widely used in automotive applications for protecting wires, reducing vibration, and ensuring durability.
What is the difference between natural rubber and polyurethane grommets?
Natural rubber grommets offer good flexibility and elasticity, while polyurethane grommets provide higher strength, durability, and resistance to wear and chemicals.
What are rubber grommets used for?
Rubber grommets protect cables, wires, tubes, and hoses from sharp panel edges. They also provide strain relief, vibration damping, and protection against dust and moisture.
Which materials are used to manufacture rubber grommets?
We manufacture rubber grommets in Natural Rubber (NR), Nitrile (NBR), EPDM, Silicone, and TPE, depending on the application requirements.
Can you manufacture custom rubber grommets from a drawing or sample?
Yes. We manufacture custom rubber grommets from 2D/3D drawings, physical samples, or required dimensions.
How do I choose the right rubber grommet size?
You need to consider the cable or tube diameter, panel hole diameter, and panel thickness when selecting the correct grommet size.
What is the difference between open and closed (blind) grommets?
Open grommets have a center hole for cables, wires, or hoses, while closed or blind grommets seal unused panel openings.
Do you supply standard and custom rubber grommets?
Yes. We supply standard sizes as well as custom grommets made to the required dimensions, hardness, and rubber compound.
