The Husqvarna 510242901 O-Ring Outside Tank Nipple is a genuine OEM sealing component designed for the WT15i water tank. This replacement o-ring delivers an exact dimensional match to the original, ensuring a secure, leak-free seal at the outside tank nipple connection. DHS Equipment supplies this part to help keep your water tank performing at full capacity.
Key Features
- OEM-Spec Elastomer Construction — Manufactured to Husqvarna's original material and compression specifications, ensuring correct sealing force and chemical compatibility with water-system components.
- Drop-In Replacement Fit — Sized to match the original groove dimensions at the outside tank nipple, allowing this o-ring to seat properly without modification to the fitting or housing.
- WT15i Water Tank Compatibility — Confirmed fitment for the Husqvarna WT15i pressurized water tank, used in wet-cutting and dust suppression applications on construction sites.
- Leak-Free Seal Restoration — A worn or degraded o-ring at the tank nipple allows water to escape under pressure, disrupting wet-cutting flow and creating slurry control issues; this part restores the integrity of that connection.
- Pressure-System Safe — Engineered to withstand the operating pressures of the WT15i water delivery system, making this a critical sealing component rather than a cosmetic one.
The outside tank nipple o-ring forms a compression seal between the nipple fitting and the tank body, preventing water from bypassing the joint under operating pressure. When this o-ring hardens, cracks, or deforms with age and use, the seal is compromised and water loss at the fitting follows — reducing flow to the blade and undermining slurry suppression. Replacing it with a genuine OEM part restores the tight, pressure-rated seal the WT15i was designed to maintain.
