*PRODUCT IMAGE IS REPRESENTATIVE PROVIDED BY THE MANUFACTURER. DO NOT MAKE BUYING DECISIONS SOLEY BASED ON THE IMAGE. PLEASE VERIFY SPECIFICATIONS MEET YOUR REQUIREMENTS.
ST Series high flow Couplers (hydraulic, fluids) up to 6700 psi connect with ST Series high flow Nipples.
Parker's ST Series are unvalved quick couplings with manual sleeves providing high flow and low pressure drop. The smooth, straight through flow path allows easy cleaning where the same lines are used for more than one media. These straight through couplers and nipples are available in a wide range of sizes and materials for pressure ranges up to 6700 psi.
Technical Characteristics:
• Sizes: 1/8” – 1-1/2”
• Materials: Brass, 303 Stainless Steel
• Port Ends: Female NPTF, Male NPTF
• Seal Options: Nitrile, EPR, Fluorocarbon, Neoprene
Other Coupler options include: Sleeve lock
Markets:
• Industrial
• Construction
• Commercial Cleaning
• Agriculture
Features/Benefits:
• Multi-purpose high flow coupling, widely used in varied applications
• Wide range of sizes and material options
• Optional coupler sleeve lock helps to prevent accidental disconnection
• Functionally interchanges with similar straight through quick couplings
Applications:
• High pressure water
• Steam washers
