What HEYCO is known for
HEYCO (HEYCO Products) is a specialist manufacturer of molded wire-protection components, electrical bushings and cordgrips. The brand is widely used where cables, cords and harnesses pass through panels, enclosures or conduit — providing mechanical protection, strain relief and environmental sealing. HEYCO’s portfolio includes snap and universal bushings, dome and HEYcaps/plugs, strain-relief cordgrips (including liquid‑tight designs), conduit fittings, and a range of grommets and seals. The company operates as part of the PennEngineering family and publishes technical catalogs, parts pages and datasheets for procurement and design use.
Main product families and technologies
- Snap and universal bushings: fingertip‑install snap bushings and universal/open-closed bushings for knockout and panel holes in a wide range of diameters and panel thicknesses; many are molded in Nylon 6/6 for durability.
- Liquid‑tight cordgrips and Tite/HEYco‑Tite series: straight‑thru, pigtail and right‑angle cordgrips with NPT, PG and metric hubs; available in nylon, metal and hybrid stainless/nylon constructions and with TPE sealing glands for improved environmental sealing.
- Strain reliefs and cordgrips: straight-thru, pigtail and in‑line styles designed for specific cable types, often UL‑recognized where required.
- Plugs, HEYcaps and hole seals: solid and break‑thru plugs, low‑durometer TPE plugs for liquid‑tight applications and split plugs.
- Conduit fittings and accessories: fittings designed for corrugated liquid‑tight conduit, locknuts and related hardware.
Typical commercial and industrial applications
HEYCO parts are specified across many trades and industries: electrical panel builders, controls and instrumentation, HVAC and appliance manufacturers, renewable energy installations, OEM equipment and contract manufacturing, facility and security enclosures, and field maintenance/repair work. Applications include protecting conductors at knockout openings, providing strain relief for power and control cords, sealing cable entries against dust and moisture, and finishing unused knockout holes with plugs.
Design and procurement features buyers should check
- Fit dimensions: mounting hole diameter, panel thickness range, and maximum cable/bundle OD are the primary selection parameters.
- Material and environment: Nylon 6/6 and thermoplastic rubber (TPE) are common; choose TPE or low‑durometer plugs for liquid‑tight sealing.
- Thread type and trade size: cordgrips are offered with NPT, PG and metric hubs; match the hub type to the enclosure.
- Certifications: many HEYCO components are UL Recognized — always confirm the specific part datasheet for applicable file numbers.
How Safsale helps procurement and model identification
Safsale’s HEYCO listing page aggregates product listings, images and specification cues to speed identification and sourcing:
- Part search and SKU listing: Safsale lists 13 HEYCO SKUs, including common bushing and cordgrip items; search by HEYCO part number or descriptive size identifiers.
- Images and gallery: photos show part geometry, shutter styles and sealing glands for visual confirmation.
- Datasheets and PDFs: product pages include manufacturer datasheets and catalog excerpts so teams can confirm dimensions, materials and approvals.
- Reviews and Q&A: buyer feedback highlights real‑world fit notes and installation tips.
- Cross‑reference and replacement guidance: when the original part number is missing, measure mounting hole diameter and panel thickness and compare to HEYCO dimension tables to find equivalents.
Sourcing and replacement best practices
- Confirm part numbers and datasheet dimensions before ordering.
- Verify UL file numbers and certificates for safety‑critical installs.
- Measure mounting hole and cable OD when replacing unknown bushings and request samples for fit verification.
- For OEM or custom needs, consult manufacturer resources for CAD files and molding tolerances.
Why buyers choose HEYCO parts
HEYCO’s deep product line, published technical data and consistent sizing conventions make it a common choice for panel penetrations and cord protection across industrial and OEM applications. If you need help identifying a replacement from Safsale’s HEYCO listings, provide a photo of the installed part, the mounting hole diameter and the cable/bundle OD — Safsale’s procurement team can then match datasheets and recommend appropriate SKUs or alternatives.
