Delavan Dela-Fitâ„¢ Quick-Connect Industrial Spray Nozzles:
Engineered for Tool-Free Maintenance and Perfect Alignment Retention.
Delavan Dela-Fitâ„¢ Quick-Connect Industrial Spray Nozzles are high-performance modular component systems designed to streamline fluid manifold maintenance across high-impact washing, coating, and industrial processing operations. Engineered around a proprietary tool-free cam-locking architecture, the system separates the permanently plumbed receiver bodies from interchangeable, single-piece spray tips. By replacing traditional NPT/BSP threaded connections at the nozzle interface, the Dela-Fitâ„¢ ecosystem provides plant and plant-automation engineers with a robust, zero-leak fluid distribution solution that completely eliminates the labor, mechanical wear, and alignment errors common during routine spray-header maintenance loops.

How it Works
Quick-Attach Cam Mechanics & Modular Architecture
The Dela-Fit™ system functions via a two-part mechanical connection—permanently plumbed header bodies and swappable spray tips—to isolate tool labor from the fluid manifold path:
Dela-Fitâ„¢ Permanent Header Plumbing: Robust Dela-Fitâ„¢ receiver bodies are threaded or welded permanently onto the system’s liquid distribution pipework. Because these base units remain static, the pipe header threads are never subjected to repeated cross-threading or mechanical stripping during nozzle replacements.
Tool-Free Hexagonal Cam Engagement: The spray tips feature a specialized, single-piece hexagonal quick-attach body. Technicians lock or release the nozzle tip inside the receiver body by hand with a simple twist, completely removing the need for spanners, wrenches, or thread sealants.
Dela-Fit™ System — Cross-Milled Alignment Locking: Unlike standard threaded nozzles where the final spray angle depends on thread torque, the Dela-Fit™ system integrates a rigid, physical alignment register. When a flat fan or directional tip is twisted into the body, it naturally seats into an exact, non-negotiable target orientation, guaranteeing that the spray pattern matches the design specifications of the header every single time.
Key Features & Benefits
Rapid Tool-Free Maintenance: Designed to drastically slash operational downtime in demanding, debris-heavy environments like gravel/coal washing, metal pre-treatment, or dust suppression headers.
Automatic Pattern Realignment: Eliminates manual header re-aiming by maintenance crews; replacement tips automatically lock back into their precise geometric alignment vector upon installation.
Tapered Anti-Clogging Inlets: Nozzle tips are manufactured with a specialized tapered internal inlet geometry that reduces fluid shear wear and actively minimizes the risk of particulate clogging.
High-Efficiency O-Ring Sealing: Uses integrated internal EPDM seals (standard) or Viton seals (optional) inside the body to prevent hydraulic pressure drops without relying on shreddable Teflon tape or thread compounds.
Modular Spray Versatility: Enables engineering teams to completely alter a manifold’s hydraulic profile (e.g., swapping a high-impact wash to a solid cone mist) in minutes by swapping tips while keeping the underlying header intact.
