The round gauge stands proud on top and is easier to read from an angle. Both cover the same pressure range — the choice is about where the operator stands.\u003c\/p\u003e\n\n\u003ch3\u003eReplacing an AR(K)-B unit\u003c\/h3\u003e\n\u003cp\u003eThe D series is the direct successor to the AR(K)-B, discontinued by SMC in March 2025. Panel mounting, brackets and set nuts carry over, so an existing installation usually takes the new unit without rework. Tell us the old code and we will confirm the matching D specification.\u003c\/p\u003e\n\n\u003ch3\u003eOrdering\u003c\/h3\u003e\n\u003cp\u003eOrder by the full code \u003cstrong\u003eAR20K-F02BE-D\u003c\/strong\u003e. The K marks the reverse flow function, F02 the port thread, and BE the bracket and embedded gauge — one character changes the part.
