This rubber bushing is purpose-built to protect conductors and cables as they pass through panels, housings, or clamps. With a precise inner bore of 7/32 in, it accommodates smaller-diameter wires or pass-through conduits while the 3/4 in outer diameter and 0.31 in wall thickness create a secure, vibration-damping barrier against edge abrasion, moisture, and wear. The underground-rated construction and multiple safety listings mean it’s ready for challenging environments where reliability matters.
Why this Jandorf bushing stands out
-
Certified safety and reliability: UL, CSA, and ETL listings assure code compliance and consistent performance over time.
-
Underground-rated construction: Built to withstand damp conditions and exposure typical of buried or exposed installations.
-
Convenient packaging: Carded packaging with 3 bushings per unit makes stocking and selecting straightforward on job sites.
Use cases and applications
- Electrical enclosures and panels where a 3/8 in trade-size bushing is needed to insulate and protect conductors as they pass through metal surfaces.
- Junction boxes in environments with moisture or buried installations that require robust insulation and edge protection.
- Small-diameter conduit or cable runs that benefit from vibration dampening and abrasion resistance.
Practical installation tips
Before installation, verify that the bore size matches your conductor or conduit. Align the bushing so the smooth, rubber surface sits against the edge or panel, then press firmly into the opening until seated. The insulating material helps prevent wear and galvanic corrosion, contributing to a longer-lasting wiring run.
