Connector O-Rings
Weatherproof connector O-rings and face seals for RF and power connectors, ozone and UV resistant.
Application Overview
RF and power connectors on outdoor cabinets rely on O-rings that stay elastic through decades of thermal cycling. We supply standard and custom O-rings in low-compression-set silicone, plus bonded washers for bolted flange interfaces. Material certificates with lot traceability ship with every order for installer QA.
Technical Standards
- ✓IEC 60529 IP68 sealing performance in customer interfaces
- ✓Low compression set (<10%, 70 h at rated temperature) compounds
- ✓Ozone resistance per ASTM D1149; UV stable
- ✓ASTM D2000 material call-outs supported
Manufacturing Process
O-rings are injection or compression molded; bonded seals are metal-rubber overmolded in-cycle.
- Custom cross-sections and non-standard IDs from dedicated tooling
- Bonded washers cure rubber directly onto zinc-plated steel — no adhesive failure mode
- Post-cure for stable compression set performance
- Kit packaging (per-connector bagging) available
Quality Inspection
- 🔍100% visual inspection (flash, short-shot, contamination) before packing
- 🔍Dimensional verification against approved drawing; FAI report on first shipment and after any tooling change
- 🔍Hardness per ASTM D2240 (Shore A) on every batch
- 🔍Lot traceability: material batch, cure records and operator logged for every carton
- 🔍Compression set per ASTM D395 (70 h) on qualification lots
- 🔍Cross-section and ID verification per lot
- 🔍Bond pull-off sampling for bonded seals
- 🔍Hardness per ASTM D2240 per batch
