Bushes & Grommets
The Ionnic range of quality snap in nylon bushings are quick and easy to install, the one piece design provides cable retention and provides strain relief. Ionnic EPDM rubber grommets are also a one piece design that when drilled to suit your cable sheath diameter provides an environmental seal to IP67 and acts as a strain relief, the EPDM rubber is chemical resistant and halogen free. Both ranges are suitable for automotive and marine bulkhead cable terminations.

Advanced Snap-In Nylon Insulation and Mechanical Strain Relief
Routing multi-strand copper cables or complex wiring loops through raw, sheet-metal bulkheads introduces severe physical risks, as sharp panel edges can quickly slice through primary wire insulation and trigger catastrophic short circuits against the chassis. Our high-performance Ionnic Nylon Bushings completely overcome these structural vulnerabilities by functioning as a smooth, durable secondary barrier that snaps firmly into place. Featuring an innovative one-piece mechanical molding, these trade-grade nylon bushings are quick and easy to install, delivering reliable cable retention while providing excellent strain relief to ensure wires cannot rub or pull against raw metal boundaries under intense machinery movement.
IP67 Waterproof EPDM Seals and Chemical Defense
Achieving total safety and matching code compliance across marine hulls, vehicle firewalls, and exposed industrial enclosures requires a flexible sealing barrier capable of blocking harsh external elements. Our high-performance Ionnic EPDM Rubber Grommets feature a one-piece design explicitly engineered to deliver an exceptional level of environmental protection. When drilled cleanly to suit your exact cable sheath diameter, these premium rubber grommets compress tightly to form a certified waterproof and dustproof seal to rigorous IP67 standards. Manufactured from premium ethylene propylene diene monomer (EPDM) compounds, this rugged rubber is entirely halogen-free and possesses outstanding chemical resistance, allowing it to withstand prolonged under-bonnet heat, grease, mechanical oils, and saltwater spray without becoming brittle, cracking, or degrading over years of heavy service.
Frequently Asked Questions
When should I choose a snap-in nylon bushing over a rubber grommet?
Snap-in nylon bushings are the ideal choice for rapid, dry applications inside commercial control cabinets, dashboard internal firewalls, and protected structural panel paths where quick cable retention and smooth mechanical strain relief are the primary requirements. EPDM rubber grommets should be deployed when your wiring loops pass through exterior boundaries, engine bays, or marine bulkheads that require a completely watertight and dust-tight seal to protect internal compartments from the elements.
How do I install the Ionnic EPDM grommets to achieve an IP67 waterproof rating?
To establish a certified IP67 environmental seal, you simply snap the one-piece EPDM grommet into your pre-drilled panel hole. Next, utilizing a standard workshop drill bit or punch, you create a central opening in the rubber web that is slightly smaller than the outside diameter of your target cable sheath, ensuring the flexible rubber stretches and clamps tightly around the jacket to form an unyielding moisture barrier.
Are Ionnic rubber grommets safe for marine use?
Absolutely, both product lines are specifically engineered to thrive across demanding automotive and marine settings. The high-grade nylon 6/6 formulation and advanced EPDM rubber matrix possess superior material memory and outstanding resistance to atmospheric oxidation, salt-air exposure, ultraviolet rays, and aggressive workshop cleaning solvents.
Does the EPDM rubber release toxic fumes if the circuit overheats?
No, our genuine Ionnic EPDM rubber grommets are manufactured using a specialised, halogen-free compound. In the event of extreme localised electrical overheating, an inline terminal fault, or exposure to external engine bay flames, the rubber will not release highly toxic, corrosive, or acidic halogen gases, safeguarding your personnel and nearby sensitive diagnostic equipment.
