Proven Receptacles for Natural Gas Vehicles Worldwide
Renowned vehicle manufacturers have trusted WEH for years – from production vehicles and buses to heavy-duty commercial vehicles with CNG drives. WEH® receptacles enable safe, quiet, and fast refueling with compressed natural gas (CNG) at 200 or 250 bar. With precisely matched connection geometries, they are compatible with NGV1 fueling nozzles according to ISO 14469 and ANSI NGV1 standards.
High Safety & Minimal Downtime – In Daily Fleet Operation
Whether CNG receptacles for passenger cars, buses, or trucks – all variants impress with their robust stainless steel construction, aerodynamically optimized flow design, and integrated check valve mechanism. Wear-resistant seals prevent leaks and ensure long-term reliability. Depending on requirements, bulkhead fittings, internal or external threads, as well as ACME and UNF connections are available. Complementary CNG filters enhance system cleanliness and protect against particles – for a durable and reliable CNG infrastructure.
