For your reference, here are the WL series models we typically use for Sealed un3373-case applications. Outer dimensions (OD) are measured to the outside of the case; inner dimensions (ID) reflect the usable cavity after subtracting wall thickness. All in millimeters; imperial dimensions in our catalog PDF.
| Model | Outer (mm) | Inner (mm) | Weight (g) | Material | Size Class |
|---|---|---|---|---|---|
| WL2305 | 230×180×45 mm | 225×150×40 mm | 240 g | PP+PC | First Aid Kit |
| WL3812 | 380×320×120 mm | 365×280×110 mm | 1100 g | PP+PC | Vaccine Carrier |
| WL5020-D | 500×400×200 mm | 480×360×185 mm | 2400 g | PP+PC+VIP | Cold Chain 96h (2-8°C) |
The most common model for "Sealed un3373-case" buyers is the WL2305 (230×180×45 mm OD, 240 g empty weight, PP+PC body).
Sealed un3373-case shells are rated -40°C to +80°C per MIL-STD-810H Method 501.7 (high) and 502.7 (low). Chemically resistant to petroleum, mineral oil, dilute acids, alcohols, and most industrial solvents. Not resistant to concentrated sulfuric acid, aromatic, or chlorinated solvents.
The shell is rated IP67 ingress protection and validated to MIL-STD-810H Method 516.8 (26 drops at 1.5m). Temperature range is -80 ~ +50 (depending on PCM/VIP configuration) °C. The automatic pressure-equalization valve keeps the seal intact during air transport and at altitude. Latch is a double-throw design rated for 5,000 open/close cycles. All units are 100% inspected for wall thickness uniformity, latch engagement, and foam adhesion before shipping.
In 2024, we shipped Sealed un3373-case for: (1) Film production — ARRI Alexa Mini + accessories in custom foam. (2) Drone operators — DJI Mavic 3 + RC + 6 batteries. (3) Broadcast — RED Komodo + 2 lenses + monitor. (4) Military — rifles + scopes + ammo. (5) Medical — first aid kits + AED.
When evaluating Sealed un3373-case options, focus on three metrics: (1) Foam density — cheap cases use 15 kg/m³ foam that bottoms out; ours is 25 kg/m³, 5+ year use. (2) Latch cycle rating — cheap plastic latches break after 200 cycles; ours is metal-reinforced, 5,000 cycles. (3) IP certification — every batch ships with serialized IP test certificates.
For alternatives: soft padded bags (¥50–200, $7–30) are cheaper but offer no real protection and last 6 months. Aluminum hard cases ($80–300) are heavier, prone to denting, and 2–4× the price. Carbon fiber cases ($300+) are overkill for 95% of B2B use cases. Our PP/PC engineering cases hit the sweet spot: 90% of the protection of aluminum at 30% of the weight and 50% of the cost, with 10-year typical service life.
To order Sealed un3373-case: (1) Email kexin@beeaa.com or WhatsApp +86 13590555309 with your equipment specs and quantity.

ISO 9001:2015, ROHS, CE, FCC, IP67/IP68, MIL-STD-810H, UN 3480 (LiPo battery transport), WHO PQS pre-qualification (medical), REACH. All renewed annually and available as PDF.
5-stage QC: 100% surface resistance / dimensional check, 26 drops at 1.2m + water submersion, -40 to +80°C × 12 cycles, 5,000 latch cycles, 1,000 pressure valve cycles. Lot certificates traceable by serial number.
Both protect against dust (6 = dust-tight). IP67 = submersible 1m / 30 min. IP68 = submersible beyond 1m (typically 3-5m) / continuous. IP68 costs ~15% more due to reinforced seals and pressure valves.
ASTM B117 standard, 96 hours continuous salt spray (5% NaCl solution at 35°C). After 96 hours, no visible corrosion on metal parts, no delamination of surface coating. Standard for all outdoor-rated models.
UV exposure test per ASTM G154: 500 hours accelerated UV exposure (UVA-340 lamp, 60°C). After 500 hours, color shift ΔE < 2.0, no cracking, no chalking. Suitable for outdoor storage and direct sun exposure.
