Festo
543821
Manifold block CPE10-PRS-1/4-2
The Festo 543821 is an industrial component featuring a wrought aluminum alloy manifold rail with a width dimension of 16 mm and a product weight of 131 g. It supports any mounting position via through-hole manifold block mounting and internal thread pneumatic valve mounting, accommodating up to two valve positions and two pressure zones with pneumatic connections G1/4 for ports 1, 3, and 5. Operating within a temperature range of -5 °C to 50 °C for both the medium and ambient environment, it withstands an operating pressure of -0.09 MPa to 1 MPa and a burst pressure of 5 MPa, while achieving a corrosion resistance class of CRC 2 and RoHS compliance.

Request a QuoteWhy no listed price?
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 Festo references — within one business day.
