Installation Position
The European standard filling port (manhole cover), also named Aluminum alloy oil tanker truck manhole cover and Flange-type tank car manhole cover, is bolted onto the top flange of oil tanker tank bodies. The Flange-type tank car manhole cover relies on evenly distributed bolt holes with 540mm center spacing to realize full-surface fitting with tank opening flanges. The Aluminum alloy oil tanker truck manhole cover forms a fully sealed access port, and the European standard filling port (manhole cover)’s built-in breathing valve fits the inner tank cavity to balance internal pressure during fuel loading and transportation.

Our Aluminum alloy oil tanker truck manhole cover, European standard filling port (manhole cover) and Flange-type tank car manhole cover are core safety sealing components for fuel tank vehicles:
1
Highway fuel tank transport
580mm European standard filling port (manhole cover) fits large gasoline and diesel tankers. The Aluminum alloy oil tanker truck manhole cover prevents liquid leakage and volatile gas escape on bumpy roads, while the Flange-type tank car manhole cover eliminates static risks of flammable cargo.
2
Factory fuel transfer tankers
Built-in breathing valve adjusts tank pressure during fast loading and unloading. The wide temperature resistance of Aluminum alloy oil tanker truck manhole cover adapts all climate zones, and the flange structure meets EU hazardous liquid transport standards.
3
Chemical transport tankers
Aluminum alloy material resists fuel corrosion. Pressure relief design of European standard filling port (manhole cover) avoids tank deformation from thermal expansion, and leak-proof Flange-type tank car manhole cover complies with international transport rules.

Product Introduction
European standard filling port (manhole cover), generally known as Aluminum alloy oil tanker truck manhole cover or Flange-type tank car manhole cover, is a dedicated flange-mounted sealing manhole assembly for fuel tank trucks under European safety standards. This Jiada brand Aluminum alloy oil tanker truck manhole cover adopts 580mm overall diameter with 540mm standard flange hole spacing, manufactured from integrated cast aluminum alloy with deep space gray anti-corrosion surface treatment. Each European standard filling port (manhole cover) is equipped with an internal breathing valve, supporting automatic exhaust between 21–35kPa emergency vent pressure and maintaining zero leakage above 20kPa. The Flange-type tank car manhole cover owns static conductive performance ≤5Ω and 65kPa nominal pressure resistance, providing sealed inspection, cleaning and fuel filling access for tanker tanks while controlling volatile fuel vapor emissions.

Product Advantages
Full EU safety compliance: All Aluminum alloy oil tanker truck manhole cover pass pressure and static tests. European standard filling port (manhole cover) meets EU hazardous goods rules, and Flange-type tank car manhole cover integrates pressure relief, static elimination and anti-leakage functions.
Tight leakproof sealing structure: Precision machined sealing face fits tank flanges closely. Aluminum alloy oil tanker truck manhole cover stops fuel spillage under pressure swings, and its sealing ring works stably at -20℃~50℃.
Integrated breathing valve assembly: Each Aluminum alloy oil tanker truck manhole cover comes with a breathing valve for automatic pressure balance. The small cover of European standard filling port (manhole cover) exhausts under emergency pressure to prevent tank deformation.
Anti-static alloy housing: Static resistance ≤5Ω eliminates static hazards. Lightweight rigid Aluminum alloy oil tanker truck manhole cover resists impact and corrosion, and integral casting avoids weak welding seams.
Universal flange dimension: 580mm diameter and 540mm hole spacing fit most global tanker tanks. Aluminum alloy oil tanker truck manhole cover supports direct bolt replacement to simplify maintenance.
