Molded pass-through parts for cables, tubes and panel openings, with panel fit, bore contact and insertion requirements defined.
A grommet fits both the panel opening and the cable or tube passing through it. Identify the panel thickness and hole profile alongside the pass-through diameter. An overall outside diameter cannot describe retention or cable contact.
State whether the part is intended for edge protection, routing support or a tested environmental seal. A soft pass-through does not by itself establish strain relief, electrical insulation or an ingress protection level. Include the complete assembly acceptance test if these functions are required.
Review cable movement, contact with lubricants or cleaning agents, visible finish and allowable insertion force. Thin webs, multiple holes and complex panel contours should be represented in the drawing before sampling.
Only after the design owner checks the required sealing, retention and electrical functions. Similar appearance does not establish equivalence.
It defines the retention groove fit and helps prevent a loose or difficult-to-install part.
SPECIFICATION REFERENCE
These are project discussion inputs. Compound, tolerances and validated performance require agreement for the specific part.
| Selection / definition | Reference and project conditions |
|---|---|
| Panel interface | Hole contour and panel thickness in mm, including tolerance |
| Pass-through | Cable/tube OD range, count and spacing in mm |
| Retention | Groove width/depth, flange geometry and pull-out requirement |
| Assembly | Insertion direction, allowable force and permitted aids |
| Exposure | Indoor/outdoor conditions, fluids and temperature in °C |
| Functional test | Protection, movement, sealing or retention criteria for the assembly |
KNOWLEDGE & SELECTION
Knowledge
A practical procurement guide to the installation details that drawings and material names often miss. Learn what to specify for pump tubing, formed elbows, reinforced hoses, appliance connectors, automotive ducts, closures, flexible seals and gaskets—and where product-family descriptions stop short of proving suitability.
