Parker FF‑501‑8FP + FF‑502‑8FP Flat Face Hydraulic Quick Coupler Set | ½″ Body ISO 16028 | Fits ½″ NPT & NPSF Threads | For Bobcat, Kubota, Skid Steer Attachments | 3000 PSI

The OEM Standard for Skid Steer Hydraulics.If you are looking for the cheap "throw-away" couplers, this isn't it. The Parker FF Series is the heavy-duty standard specified by OEMs for durability and flow performance. This set (FF-501-8FP + FF-502-8FP) is the exact replacement for the flat-face couplers found on thousands of Skid Steers, Compact Track Loaders, and Mini Excavators.NPSF vs. NPT - What you need to know: These couplers feature ½″ NPSF (Straight) threads. They are designed to accept standard ½″ NPT (Tapered) Male fittings. The threads mesh to create a mechanical "Dryseal" without the risk of cracking the housing that comes from overtightening tapered ports.Universal ISO 16028 Interchange: While these are genuine Parker parts, they will connect with any ISO 16028 "Flat Face" coupler of the same ½″ Body size, including those from Stucchi, Dixon, and Holmbury.Ideal Application: Replacing worn-out couplers on Standard Flow attachments: 4-in-1 Buckets, Hydraulic Breakers, Trenchers, and Stump Grinders.Technical Specifications: Body Size: ½″ (12.5mm) ISO 16028 Thread: ½″-14 NPSF (Fits ½″ NPT Male) Pressure Rating: 3,000 PSI (207 Bar) Locking: Sleeve Lock (Manual)

• GENUINE PARKER FF SERIES (OEM): Includes (1) FF‑501‑8FP Coupler and (1) FF‑502‑8FP Nipple. The exact OEM couplers used by major equipment manufacturers. Meets ISO 16028 & HTMA standards for global interchangeability with Stucchi, Safeway, and Holmbury flat face couplers.
• FITS BOBCAT & SKID STEERS: The standard ½″ Body Size fits "Standard Flow" hydraulic systems on Bobcat, Kubota, John Deere, Case, and CAT skid steers. Perfect for connecting attachments like Grapples, Snow Plows, Augers, and Brush Cutters.

• NON-SPILL FLAT FACE DESIGN: The "Push-to-Connect" dry break interface minimizes fluid loss (spillage) to less than 0.02 ml per cycle. Essential for working on turf, driveways, or environmentally sensitive job sites.
• HEAVY DUTY SPECS: Rated for 3,000 PSI continuous pressure and 12 GPM flow. Built from hardened steel with heavy zinc plating to resist rust. Locking sleeve prevents accidental disconnection when dragging hoses over rough terrain.
