Application
Solar / PV System
Cable glands, vent plugs and waterproof boxes for PV combiner boxes, inverter wiring and outdoor solar support equipment.
- Nylon, brass, stainless steel and junction box ranges
- Metric, PG and NPT thread options for export projects
- IP-rated sealing design for outdoor electrical systems
- OEM packing, samples and buyer-ready technical support

Field Problems in Solar / PV System
PV equipment is exposed to sun, rain and temperature swing, so cable entry parts must support sealing, pressure balance and repeatable outdoor maintenance.
Rain and UV at Outdoor Entries
PV combiner boxes, inverter wiring and outdoor support boxes need glands and washers that seal the cable entry instead of only filling the hole.
- Cable gland sealing range
- Washer and locknut matching
- Outdoor material review
Condensation from Temperature Swing
A sealed solar box can build pressure and moisture when day and night temperature changes are large.
- Vent plug discussion
- Box gasket check
- Unused hole sealing
Mixed Cable Diameters
PV projects often include different cable sizes, control wiring and monitoring cables that should not be quoted as one generic gland.
- Cable OD table
- Thread standard check
- Mixed-size packing
Recommended Product Mix and RFQ Data
Use this as a starting point. Exact models should be confirmed with cable diameter, drawing, box size or sample.
| Cable glands | Metric / PG / NPT nylon, brass or stainless options matched to cable OD and enclosure hole. |
|---|---|
| Vent plugs | For outdoor sealed boxes where pressure balance and condensation control need review. |
| Waterproof boxes | For combiner, monitoring or terminal protection with planned cable entry holes. |
| Sealing parts | Washers, plugs and reducers to close spare holes and improve panel contact sealing. |
| RFQ data needed | Send equipment type, box size or drawing, cable outside diameter list, thread standard, outdoor exposure, vent plug requirement, quantity and packing rule. |
Need a matched cable sealing solution?
Send thread size, cable outer diameter, material preference, quantity and application environment. We will recommend a practical model and packing plan.
