According to its official product overview, Beswick Engineering Co., Inc. manufactures pressure regulators, quick disconnects, valves and fittings for fluid power systems. The catalog also includes orifice restrictors, filters, mufflers, breathers, tubing and accessories. For engineers comparing miniature pneumatic components, the useful starting point is the specific product family and its published configuration options, rather than a broad claim that every component suits every application.
The company dates its founding to 1964 in its company background. Its applications engineering contact page lists an address in Greenland, New Hampshire. This guide explains what buyers can find in Beswick's current online catalog and which questions to resolve before specifying a part.
Fittings, valves and quick disconnects in the catalog
Beswick's fittings catalog includes barbed, compression, push-to-connect, flare and Luer lock options, along with adapters and other configurations. Its selector provides filters such as connection style, thread size, tubing size and material. Start with the connection required by the surrounding assembly, then examine the relevant product configuration rather than assuming that similar-looking fittings are interchangeable.
The miniature valve catalog lists check, needle, relief, ball, pinch and several on/off valve types. Buyers can narrow the selection by valve type, configuration and thread size. That makes the required function a useful first filter: identify what the valve must do before comparing its connection details.
The quick-disconnect range includes snap, non-latching, bayonet and screw types. Listed configurations include single shut-off, double shut-off and dry-break designs. The selector also distinguishes mating halves. When preparing a bill of materials, identify both halves and the required shut-off configuration explicitly; the product-family name alone is not a complete specification.
Choosing a miniature pressure regulator
Beswick's regulator catalog includes diaphragm and piston pressure regulators, vacuum regulators, back-pressure regulators and pressure-compensated flow controls. Its selector includes outlet pressure, flow rate and mounting style.
The company's regulator selection guide recommends considering inlet and outlet pressures, gas or liquid service, temperature, available space, operation with or without flow, and relieving versus non-relieving behavior. It also discusses single-stage and multistage designs.
Use those questions to build a requirements list before choosing a model. Record the expected operating conditions, not just one target pressure, and ask Beswick to confirm the appropriate configuration. This article does not assign a catalog-wide pressure rating or recommend a regulator for an unreviewed application.
Body materials and seals need separate review
Beswick's company overview identifies material options including brass, nickel-plated brass, 303 and 316 stainless steel, aluminum and titanium. That is a company-level list, not a statement that every product is available in every material.
Seal selection deserves its own check. The O-ring guide identifies Buna-N as the standard elastomer for most Beswick products and describes alternatives including fluorocarbon, silicone and EPDM. It discusses different material properties and temperature ranges. Ask for confirmation of the selected body and seal combination for the actual fluid and operating conditions, rather than treating a general materials guide as product-specific approval.
Custom components and engineering support
Beswick's custom-products page says it develops custom fittings, quick disconnects, valves and pressure regulators, and modifies standard catalog items for specific applications. Published examples include coated two-stage regulators and a flat-face quick disconnect.
For an inquiry, prepare a drawing or connection description, available space, fluid, operating conditions and the catalog item closest to the requirement. Ask which changes are feasible and what documentation accompanies the proposed configuration. These are suggested buyer questions, not promises about pricing, delivery times or qualification.
Beswick lists an Applications Engineering Department at 284 Ocean Road, Greenland, NH 03840-2442, with telephone 603-433-1188 and email techsupport@beswick.com on its engineering contact page. Use that official channel for current specifications and application questions.
