Hosco

Heritage: Built for Paint, Not Adapted From Something Else

Hosco Fittings was founded in 2010 in Wixom, Michigan, to solve a problem that most finishing equipment suppliers treat as someone else's responsibility: the fluid path between the paint room and the spray gun. Industrial facilities had long been building paint circulation systems with standard industrial fittings — threaded connections, ball valves, and hose fittings designed for water, air, or hydraulic fluid. Those fittings work for their intended purpose. They were never engineered for paint.

Standard industrial fittings have recesses, crevices, and rough interior surfaces. Paint — particularly high-solid, metallic, or two-component paint — accumulates in those dead zones, hardens, and eventually breaks free as contamination. In a high-volume automotive OEM plant or aerospace coating line, a single compromised fitting upstream can generate defects across an entire production run. Hosco was built around one engineering principle: a fitting designed specifically for paint should have no cavities, no dead zones, and no interior surface rough enough to trap material.

In April 2019, Carlisle Fluid Technologies acquired Hosco alongside Integrated Dispense Solutions (IDS) and Classic Precision, adding paint-specific fluid path engineering to a portfolio that already covered guns, pumps, and circulating systems. When Carlisle's finishing brands unified under the Binks name in 2024, Hosco moved forward as part of that platform — completing a single-source offering that now spans from the pump through the hose through the gun.

What Hosco Makes: The Fluid Path, Engineered for Paint

Hosco is the only manufacturer in the world offering both inch and metric smooth-bore, cavity-free, micro-finished valves and fittings designed specifically for paint circulation and application systems. That distinction — purpose-built for paint, not adapted from general industrial components — is the reason Hosco products appear in automotive assembly plants, aerospace coating lines, and high-volume industrial finishing operations that cannot tolerate contamination.

Every Hosco component is built around the same three principles: smooth bore (large-diameter, unobstructed flow passages that minimize shear and pressure drop), cavity-free construction (no recesses where paint can accumulate or pack out), and micro-finished interior surfaces (preventing adhesion of paint solids). The product line covers the complete fluid path from paint room to spray gun:

• Ball valves (SSBV and HBV series) — 304/316 stainless steel encapsulated ball valves with a smooth-bore, cavity-free 0.280" (7mm) flow passageway and 1/4-turn operation. Rated to 1,000 PSI / 70 bar with adjustable packing. The compact and ultra-compact configurations fit into tight manifold and circulation system layouts where full-size industrial valves won't fit.
• Fittings and adaptors — smooth-bore inline, 45°, and 90° configurations in connection sizes from 1/8" to 1/2" across NPT, NPS, JIC, compression, and metric standards. The full range of thread standards in a single product line means Hosco can standardize a multinational facility's paint system hardware regardless of whether the facility was built to inch or metric specifications.
• Quick disconnects — bayonet-style tool-free connectors in 304/316 stainless steel, rated to 300 PSI, in 1/4" and 3/8" NPS, NPT, and BSP configurations. The precision-machined design eliminates the interior cavities that trap paint in standard quick-connect bodies, preventing the sludge buildup and contamination that degrades color-change performance in circulation systems.
• Flow restrictors and regulators — stainless steel inline restrictors for regulating paint flow to individual spray guns and applicators, available in internally and externally adjustable versions. The externally adjustable RIL-6-AJ and RY-6AJ models allow precise flow setting with a 3mm hex key without opening the fluid path, covering the full range from complete shutoff to over 1,000 cc/min. Circulating and non-circulating versions available.
• Paint and air hoses — hose assemblies in nylon, FEP, PTFE, PFA, polyurethane, and EPDM in sizes from 3/32" to 2", with Hosco's barb-and-nut retention system providing a secure, leak-free connection. Nylon hose fittings are silicone-free and non-conductive, making them suitable for electrostatic finishing applications.
• Coaxial hose assemblies — assemblies that deliver the appearance of a single hose while maintaining full recirculation capability with heated flush options, for robotic and automated finishing lines where hose management and thermal control of material are both required.
• Compression and instrumentation fittings — 316 stainless steel instrumentation-grade fittings with full heat-code traceability and third-party TÜV certification, for installations requiring documented material traceability and code compliance.
• RE-Con Applicator Cleaner — a robotic containment system that efficiently cleans and dries bell applicators and automatic spray guns between color changes using solvent or waterborne cleaning media. Reduces downtime and solvent consumption in automated finishing cells.

Why CET for Hosco

Every other brand CET carries delivers coating to a surface. Hosco makes sure that coating arrives clean. A Binks pump or Wagner circulating system that's routing paint through standard industrial fittings is introducing a contamination risk that no gun or filter downstream can fully correct. Hosco's cavity-free, paint-specific fluid path components are what close that gap — and as part of the Binks platform alongside CET's pump, gun, and fluid handling inventory, Hosco is available from the same source as the rest of the system.

• System-level specification. Selecting the right Hosco fitting, valve, or hose for a paint circulation system requires understanding the coating being run, the system pressure, and the connection standards in the facility. CET specifies Hosco components alongside the pumps, tanks, and guns they feed — not as an afterthought.
• Inch and metric in one source. Hosco is the only manufacturer covering both standards in cavity-free paint fittings. For facilities with mixed-standard equipment — common in automotive OEM plants and aerospace operations with global supply chains — CET can source the complete fitting inventory from a single Hosco line.
• Parts stocking for production continuity. Quick disconnects, flow restrictors, ball valves, and hose fittings are wear and maintenance items in any active paint circulation system. CET stocks Hosco's core product line so a failed fitting doesn't become a line-down event.

From a single gun-side restrictor for a manual spray station to a full palette of cavity-free fittings for an OEM circulation system — Hosco is the fluid path component that makes the rest of the finishing system perform as intended.
