Product Description
Hardy 1329263 HREUN005SP35 Drag O-ring
The Hardy 1329263 Drag O-ring (Style No: HREUN005SP35) is a vital sealing and tensioning component used in the drag assembly of Hardy’s modern high-performance fly reels. This O-ring serves two primary purposes: it acts as a moisture and debris barrier for the internal drag stack, and it provides "stay-set" tension for the regulator knob, ensuring your drag setting doesn't drift during the vibration of a long run.
Manufactured from a high-grade, chemical-resistant elastomer, this O-ring is designed to maintain its elasticity even after years of compression and exposure to UV rays and temperature fluctuations. Replacing a cracked or flattened O-ring is essential for maintaining the waterproof integrity of your drag housing and the tactile "firmness" of the adjustment knob.

Models This Part Fits
The 1329263 O-ring is a standard fitment for several of Hardy's "Large Arbor" and "Cassette" reel series. It is a direct OEM replacement for:
-
Hardy Ultralite DD Series: 3000, 4000, 5000, 6000, 7000, 8000, 9000, 10000
-
Hardy CLS Series (Cassette Latching System): 5000, 7000, 9000
-
Hardy Ultralite MA DD (Mid-Arbor): All Sizes
-
Hardy ASR Series: 4000 through 9000
-
Hardy MTX / MTX-S Series
Technical Note: This is Part #35 on most Hardy Ultralite and CLS schematics. It is typically located behind the drag regulator knob. If your drag knob feels "loose" or spins too freely, this O-ring has likely perished. You can confirm the exact location on your reel's exploded view at www.reelschematic.com.
Key Features
-
Environmental Shield: Prevents water, sand, and grit from entering the sensitive internal drag stack, preserving the life of the Rulon and carbon washers.
-
Rotational "Damping": Provides the necessary resistance to the drag knob so it stays exactly where you set it, even when the reel is subjected to heavy vibration.
-
UV & Chemical Resistance: Engineered to resist degradation from sunlight and common cleaning solvents or reel oils.
-
Precision Fit: Machined to exact Hardy tolerances to ensure it seats perfectly in the regulator groove without binding or bunching.
Maintenance & Lubrication
O-rings are prone to drying out and "checking" (developing micro-cracks) over time. To ensure a long life and a smooth, waterproof seal, we recommend using Deuthlon high-performance lubricants:
-
Seal Conditioning: Apply a thin coating of Deuthlon Power Grease to the O-ring before installation. This grease is specifically formulated to be "rubber-safe," keeping the elastomer supple while providing a superior waterproof barrier.
-
Smooth Adjustment: A tiny drop of Deuthlon Reel Gear Oil on the surface where the O-ring meets the regulator knob will reduce "stiction," allowing for micro-adjustments of the drag without the knob feeling "sticky."
