Confirm the exact configuration
Use the manufacturer part number and model code—not appearance alone. Connection, size, material, voltage, pressure, seal, and control options can differ within the same product family.

SMC
Source the SMC HEC003-W5A industrial component directly for your facility's specific operational needs. This verified part number corresponds to an authentic SMC assembly ready for integration into your pneumatic or fluid systems. Submit the exact part number, quantity, and application requirements to receive a formal quotation.
Industrial and obsolete parts are priced per enquiry: the final price depends on available stock, condition, quantity, and your delivery destination, so a fixed list price would be misleading. Request a quote and we confirm current pricing, lead time, and sourcing options — including hard-to-find and discontinued SMC references — within one business day.
For a faster response, include quantity, condition, and delivery destination.
