Engineered for maximum performance at minimum size. MINIATURE FLUID POWER PRODUCTS Hbeswick engineering

The Beswick difference Whatever your industry, we know that every part of your product, no matter the size, is of the utmost importance. Whether you build satellites, manufacture medical devices, or design analytical instruments there is no room for error and no time to spare due to inefficient or inferior parts. You need high performance products supported by an experienced application engineering team. See our website for additional drawings and technical specs, flow curves, as well as a full library of 3D CAD models available for download. You can also configure part options, view...

At Beswick, we understand this. Each of our products, from fittings to valves, has been carefully engineered, tested, and perfected over our 55+ years in business. Our customers know they can rely upon them to provide maximum performance and space savings within critical applications, where failure is not an option. We take great pride in our innovations over the years and being on the leading edge in miniature fluid power. Many of our design innovations have become the industry standard. We continue to innovate with our team of highly trained engineers, machinists, and technicians,...

The Beswick story Paul Beswick, our founder, was an engineer’s engineer who was known to have many projects in various stages of development, both at home and at work. Paul loved the technical aspects of engineering and design; this truly was his life’s passion. Paul worked for Itek as a project manager and department head before founding Beswick Engineering, at the time a small engineering consulting firm, in 1964. While running his engineering consulting firm, Paul continued to broaden his technical knowledge of manufacturing techniques through work with a friend who ran a contract...

The customer loved Paul’s innovative designs, and with this early success, Paul shifted his focus from an engineering service company to a fluid power products company. The company focus changed, but not the commitment and passion to solve customer problems. With orders coming in for his innovative products, Paul purchased his first automatic manufacturing machines so Beswick could manufacture its own products. Among the first products designed and produced by Beswick Engineering were fittings, pressure regulators, valves, and quick disconnects. In 1996, Beswick Engineering moved from its...

Our portfolio ofHOLE DIA. 3/32 products Beswick offers the most complete selection of miniature fittings in the industry.

High performance materials It wasn’t all that long ago when fluid power products handled only compressed air. Brass was, and still is, fine for those traditional applications, but today’s high performance applications often involve corrosive fluids such as DI water, solvents, inks, acids and bases. These modern applications require corrosion resistant and low out-gassing materials. While brass is not obsolete (we continue to offer brass products), there is a growing requirement for specialty alloys such as 303 and 316 Stainless Steel, as well as high performance elastomers. These materials...

MATERIAL FINISHES A bright-dip finish is standard for brass products. Our aluminum products come standard with a clear anodized finish. Our 303 and 316 stainless steel products are passivated or electropolished. Brass items can be ordered with an optional electroless nickel plated finish. Simply add "-ENP" as a suffix to the part number. Note, while we stock a large selection of nickel plated components, some are made to order, and minimum lot fees may apply. Other optional finishes and coatings can be arranged on special order basis. Contact a Beswick applications engineer to discuss your...

Beswick’s captured O-ring seal In the 1960’s, Paul Beswick originated and perfected the captured O-ring face seal used in our miniature fittings. Over the years, Beswick has further optimized this design to produce the best performance in the industry. The advantages of Beswick O-ring seal fittings: • Superior leak-tight seal compared to flat gasket or pipe thread fittings. • Compensation for rough surface finish and slight hole misalignments in mating parts. • Cleaner, more professional appearance. • Fast installation – There is no gasket that must be positioned on the fittings and no...

OPTIONAL O-RING MATERIALS Beswick fittings are supplied with Buna-N O-rings, since Buna-N satisfies the requirements of most applications. We install the O-rings at our factory, saving you the assembly costs incurred with gasket style fittings. We also offer optional O-ring materials for applications involving temperature extremes and/or chemical reactivity. To specify an optional O-ring, add the material code from the chart below as a suffix to the part number. For example, to order the popular MLAS-1012 elbow fitting with Silicone O-rings, specify MLAS-1012-S. OUR CUSTOM O-RING MATERIALS...
