About Industrial Specialties Mfg. (ISM)
Industrial Specialties Mfg. (ISM), headquartered in Englewood, Colorado, has been a trusted manufacturer and distributor of miniature pneumatic, vacuum, and fluid circuitry components since 1982. What began as a small operation filling a niche need for miniature plastic pneumatic fittings in the Denver area has grown into a worldwide supplier serving OEMs and distributors across a remarkable range of industries — from automotive and small engine to commercial/industrial, food and beverage, medical, and laboratory applications.
ISO 9001:2015 Certified Quality
ISM holds ISO 9001:2015 certification covering the manufacture, assembly, partial design, and distribution of pneumatic and fluid components for both industrial and medical applications. This commitment to a rigorous quality management system means every fitting, valve, and filter that leaves ISM meets consistent, verifiable standards — a critical factor for OEM engineers designing systems where leaks or failures simply aren't an option.
A Broad Portfolio of Flow Control Components
ISM's catalog spans more than 3,000 active SKUs, making it one of the most comprehensive sources for miniature flow control hardware available. Their product lineup includes:
- Plastic and metal fittings — including push-in fittings, barbed fittings, swivel fittings, and manifolds in a wide variety of materials to meet diverse chemical compatibility requirements
- Check valves — spring-loaded, diaphragm, duckbill, and ball-style check valves in nylon, Kynar, polypropylene, and other engineered plastics
- Miniature inline filters — including the Clear-VU EZ Connect series, designed for push-to-connect convenience in pneumatic, vacuum, and fluidic lines
- Miniature valves — flow control valves for air, gas, and fluid systems in compact, small-bore configurations
- Pressure relief valves — including the NRV and NVRT series for in-line and low-clearance pressure relief venting
- Quick disconnect couplings, mufflers, breathers, orifices, and plastic tubing
Serving the Automotive & Small Engine Markets
ISM has deep roots in automotive and small engine OEM supply. Their components are available in automotive-grade materials suited for demanding environments, and are widely used in fuel, air, and windshield system applications. For the small engine market — covering outdoor power equipment, powersports, marine, and other small engine platforms — ISM provides an extensive selection of air and fuel flow control components built to perform in varied operating conditions.
Custom Solutions & Global Reach
Beyond off-the-shelf components, ISM's engineering capabilities extend to customized fittings, kitting, sub-assemblies, and repackaging services. Their operating philosophy is straightforward: if a standard product doesn't fit the application, they will find a way to build one that does. This flexibility, combined with their scale and technical expertise, has made ISM a go-to partner for engineers solving real-world flow control challenges around the globe. In 2026, ISM was acquired by Midland Industries, further expanding their manufacturing and distribution capabilities while preserving the responsiveness and technical depth that have defined the brand for over four decades.
