Graco 172613 Stud Union Swivel

Graco 172613 Stud Union Swivel

• Compatible Machines / Systems:
• Any airless sprayer or spray rig that accepts the 172613 Stud Union Swivel style union.
• Suitable for heavy-duty painting, coating or spray foam rigs in industrial or commercial settings.

The Stud Union Swivel (Model 172613) is a precision-engineered swivel union designed to provide a secure, leak-free connection while offering full 360° rotation. It is built for demanding fluid delivery applications and is ideal wherever robust performance and reliable fluid flow are required under pressure. The swivel helps to relieve hose strain and reduces wear on connectors — a critical improvement for high-pressure spray systems and professional coating applications.

Key Features

• 360° swivel action — reduces hose stress and avoids hose twisting or kinking under load.
• Durable construction built for demanding environments (spray, coating, industrial fluid handling).
• Secure, leak-resistant union — ensures stable fluid flow and connection integrity under pressure.
• Versatile compatibility — works with a wide range of airless sprayer setups or spray rigs that accept a union-style swivel.

Installation & Usage Tips

• Ensure all mating threads and surfaces are clean before installation to guarantee a tight seal.
• Hand-start connections, then tighten to proper torque to avoid over-stress or cross-threading.
• After installation, inspect for leaks under pressure before full operation — especially important in high-pressure applications.
• If used with hoses or extensions, ensure they are properly supported so the swivel isn’t carrying excessive weight or lateral load.

Technical Overview

The 172613 Stud Union Swivel serves as a robust interface between pump output and downstream hose or manifold assemblies. Its union-style design enables easy disassembly and maintenance, while the swivel joint allows rotation to relieve torsional stress on hoses — prolonging hose and seal life. This makes it particularly suitable for industrial-scale or frequent-use spraying rigs, where durability and reliability are critical.
