What Flexline does
Flexline, founded in 1950 and headquartered at 11 Columbus Ave, Kenilworth, New Jersey, is a privately held custom manufacturer of specialty hose assemblies serving aerospace, pharmaceutical, OEM, distribution, and specialty industrial customers. The company produces stainless steel metal hose, PTFE (Teflon), silicone, composite, and rubber hose assemblies in sizes ranging from 3/16" to 24" inside diameter, with in-house capabilities spanning welding, passivation, oxygen (LOX) cleaning, and ASNT-compliant non-destructive testing including hydrostatic, pneumatic, liquid penetrant, X-ray, and helium mass spectrometer leak detection.
Flexline's product portfolio is organized across five lines: metal hose and expansion joints (including corrugated stainless steel S, H, PM, RF67, and X6 series), PTFE hose (medium, high, ultra-high pressure, gas, chlorine transfer, electrically heated, and PTFE expansion joints), sanitary and high-purity hose and fittings (rubber-covered PTFE, stainless braided PTFE, silicone, FDA/3A compliant hose, and sanitary valves from Dixon, Topline, and Newage), hydraulic and industrial products (Parker hydraulic hose, adapters, quick disconnects, brass fittings, industrial/composite/PVC hose, cam and groove fittings, dry disconnects, valves, and tubing), and qualified aerospace hose assemblies meeting SAE AS604, AS614, AS1339, AS1424, and Mil-H-25579/38360. The company maintains certifications including ISO 10380, CSA-B51-09 Annex F, FDA 21 CFR 177.1550 and 177.2600, USP Class VI, 3-A Sanitary 62-01, NSF-51, EJMA, and ASNT compliance, and serves as an authorized fabricator for Parker, Saint Gobain/Versilon, Dixon, OPW, Willcox, Titeflex, Kongsberg, and Resistoflex product lines.
Flexline generates revenue through direct-to-customer sales of custom-manufactured hardware, with quotes issued per specification rather than published list pricing. The company operates a single manufacturing facility in Kenilworth, NJ, ships 90% of orders within a day, and runs a field-sales-engineer-led go-to-market supplemented by in-house customer service and direct phone/contact-form intake. No external funding, M&A, or parent-company ownership is disclosed, and the firm has remained privately held since founding.
