113-8205 - Miller Smith Silverline Single Stage Air Regulator, CGA 346, 0-250 PSI

Technical Overview

The Miller Smith 113-82-05 is a General Purpose Single Stage Regulator from the renowned Silverline 110 Series. Engineered for non-corrosive and inert gas applications—specifically Air, Nitrogen, CO2, and Argon—this unit is built to handle the rigors of industrial environments while providing reliable pressure control. The regulator features a CGA 346 inlet connection, making it compliant with standard compressed air cylinder fittings.

Constructed from rugged brass bar stock, the body, bonnet, and gauges are fully plated (nickel) to offer superior protection against corrosion and wear. Internally, the regulator utilizes Miller's proprietary Sure-Seat™ technology. This filtered seat design is critical for maintaining gas stream purity and protecting the seat from debris, which is a common cause of regulator failure. The large 1-7/8 inch diaphragm ensures responsive and precise control of delivery pressure across the 0-250 PSIG range, despite fluctuations in cylinder pressure.

The unit is equipped with large, easy-to-read 2-1/2 inch single scale gauges that allow operators to monitor both cylinder contents and delivery pressure at a glance. With a maximum inlet pressure rating of 3500 PSIG, this regulator is compatible with high-pressure cylinders. It is not recommended for applications requiring extremely precise analytical control or where inboard diffusion is a critical concern, but it excels in general industrial, maintenance, and fabrication tasks.
