What Sinclair International does

Sinclair International is a privately held industrial supplier founded in 1925 and headquartered at 85 Boulevard, Queensbury, New York. The company designs, manufactures, and sells ancillary equipment and consumable components for paper mills, with secondary applications in cement board and glass-mat production. Its offering is organized into two divisions: a Pressure Systems Division covering shower systems (stationary, reciprocating, pipe-in-pipe, brush, Sinco-Jet, and trim-squirt variants), nozzles, filtration strainers (single in-line, duplex, multiple barrel, and Float Wash Fractionator), and the pneumatic Sinco-Guide roll/felt/wire guidance system; and a Plastics Division supplying UHMW and proprietary SP-1 through SP-5 plastic material grades, plastic covers, and custom vacuum dewatering structures (Uhle pipes, flat boxes, high-vacuum saturator pipes). Core technology centers on stainless steel and acid-resisting bronze fabrication, PLC-based automation with PID control loops, and CNC precision machining of engineered plastics differentiated by chemical and wear-resistance profiles.

Sinclair generates revenue through custom, quotation-based sales of industrial equipment rather than standardized catalog pricing, with each order engineered to specific mill requirements using data sheets submitted by buyers. Distribution is exclusively direct, executed through a regional sales-representative network covering the US Midwest (Modern Technologies), US Southeast (Mid South Mech with two coverage regions), Canada (F.P. Coinner), and Mexico (Innovapaper), with the President handling all other geographies directly from headquarters. The primary customer vertical is paper manufacturing; cement board and glass-mat are listed secondary segments. In 2025 the company secured what it described as the first CMCS-certified home-compostable product, with UK waste-management firms Envar and Biffa publicly supporting the initiative, signaling a tentative move into the circular-economy product domain. Headcount is reported in the 1-10 band, and the firm operates without disclosed external funding, public listing, or M&A activity.

Products and services

• Stationary Showers Economical fresh water or white water showers designed to provide maximum coverage for wetting, lubrication and fogging with minimal water usage in paper mills.
• Reciprocating Showers High pressure, low volume showers for paper machines, operating from 40 to 500 PSIG, available in fresh water, clarified white water brush type, or pipe-in-pipe configurations.
• Pipe-in-Pipe Showers Showers offering quick maintenance access to all shower nozzles while the paper machine is in operation, using a quick release pin for inner pipe removal without disturbing the outer support pipe.
• Brush Showers White water showers with brush and purge options for manual or automated operation, designed for contaminate buildup removal with a common brush rod system.
• Sinco-Jet Fabric Cleaning System Fabric cleaning and conditioning system using single or small cluster nozzles to jet high pressure water for removing embedded particles, with PLC controller and touch pad interface featuring Manual, Auto, Spot Clean, and Maintenance modes.
• Trim Squirt Single self-contained nozzle assembly for sheet trim applications with internal basket for last chance filtration, featuring integral disconnect/check valve for fast on-the-fly change out, available in brass or stainless steel.
