Capabilities · Grommets

Cable grommets, glands —
one stepped bung covers 4–25 mm.

TPV / EPDM / silicone cable grommets, entry seals, strain reliefs, cable glands. For control panels, switchgear cabinets, IP-rated outdoor enclosures. No MOQ on most lines. DDP UK delivery.

What we make

From one bung that fits all, to a full cable-management range.

Send a panel cut-out list, a sample part, or just the cable diameter range you need to seal. We'll quote stepped bungs, IP-rated glands, or a custom multi-cable plate to match.

Cable entry seals
  • • Stepped TPV bungs — one part covers 4–25 mm cable OD
  • • EPDM and silicone grommets — round, oval, rectangular, flat
  • • Split grommets for retro-fit on installed cables
  • • Multi-cable entry plates (Roxtec-equivalent)
  • • Bright-green visibility colour for QC / oven-cure tracking
Cable glands
  • • PA66 plastic glands — IP54, IP66, IP68
  • • Brass nickel-plated — industrial standard
  • • Stainless 316 — marine, food, pharma
  • • EMC / screened-cable variants
  • • ATEX / Ex-d certified for hazardous areas (scope confirmed at quote stage)
Cable protection
  • • Heat-shrink tubing — single + dual-wall, adhesive-lined
  • • Corrugated split conduit + smooth conduit
  • • Spiral wrap, braided sleeving
  • • Strain reliefs, flat cord grips
  • • End-of-cable boots and connector seals
Accessories
  • • Cable ties — nylon and stainless 316
  • • Cable tie mounts, cable markers
  • • Drainage plugs and breather valves (same TPV family)
  • • Conduit fittings (metric + imperial)
Stepped TPV grommets

One part, many cable diameters.

The stepped concentric profile means a single moulded part covers a 4–25 mm cable OD range — the installer cuts to the next ring up from the actual cable size. Photos and schematics shown for reference. M&J branded production samples on request.
