Hardline Products has been offering PWC parts for the personal watercraft community for more than three decades. From registration kits and racing decals to cleaning supplies and quick-install tools, our catalog covers what owners actually reach for before heading out on the water. Check out our full lineup of jetski accessories, organized by what you need to get on the water faster.
A PWC lives a brutal life. Saltwater, sun, fuel residue, sand, and high-RPM vibration all take their toll on factory parts and surfaces. That’s why every product we ship is engineered to keep your vehicle running and looking great longer. Our personal watercraft accessories use marine-grade materials, sealed enclosures, and adhesives rated for UV and submersion. If you ride a Sea-Doo, Yamaha WaveRunner, or Kawasaki, our Seadoo accessories and cross-brand jet ski parts catalog has registration decals, hour meters, install kits, and surface care formulas that match your hull.
Hardline Products is a manufacturer first, so many of the PWC products on this site were designed in-house and tested in the same saltwater and freshwater conditions our customers ride in. Our decals are digitally cut from premium marine vinyl that’s rated for years of UV and submersion. Our installation tools are billet-milled or molded to spec rather than sourced from generic suppliers. The result is a tighter, more reliable lineup of jet ski parts than you’ll find at a generic powersports counter.
Our PWC accessories break down into three core sub-categories, each focused on a specific job:
Registration Decals: state and federal-compliant PWC decals in 11 series styles and dozens of color combinations, plus 3-inch single letters and numbers, Superstick adhesive options, and clear-series options for hulls with custom graphics. Every decal is digitally cut from marine vinyl and designed for clean lines, long life, and quick application.
RX Protection and Cleaning Line: our advanced surface care system. Wash, polish, protect, and detail with an all-in-one product built for fiberglass, gelcoat, plastic, and seat vinyl. Used by racers, rental fleets, and weekend riders alike.
Products for Easy Installation: no-drill mounts, application tools, and accessory kits that turn a 30-minute project into a 5-minute project. If you’ve ever wrestled with bubbles, misaligned graphics, or stripped factory mounts, we’ve got solutions.
Owners come to Hardline for their PWC supplies for four main reasons:
Compliance: every state requires registration numbers on the hull. Our PWC decals meet legibility, height, and color requirements without the peeling and fading you’ll get from generic vinyl. We manufacture factor-matched decals that meet U.S. Coast Guard and State guidelines.
Race prep: closed-course riders run our Dirt Digit-branded reflective and high-contrast number sets so officials, spectators, and timing crews can read every pass. Our racing decals also resist the abrasion that buoy contact and water impact put on entry-level vinyl.
Detailing and resale: a clean ski sells for more. Our RX line removes fuel scum, mineral deposits, and oxidation, then leaves a hydrophobic finish that beads water for weeks. Sellers who use our cleaning system regularly before listing report faster sales and higher final prices.
Spring commissioning: replace cracked mounts, refresh registration numbers, and re-seal trim with one order from one supplier. Owners who run their PWC year-round in saltwater will find every consumable they need in one place.
Start with your registration first. Your state’s required digit height is 3 inches. Pick a color that contrasts with your hull.
Our adhesive is specifically formulated for high-friction, high-moisture surfaces, such as fresh or saltwater. From there, layer in the RX surface care kit that matches your detailing routine, plus the easy-install tools you’ll need to apply graphics cleanly. If you’re prepping a new ski, our installation kits include everything from squeegees to Sticker-On! for easy decal application and Sticker-Off! for easy adhesive removal from old decals.
If you’re a dealer or rental operator, our wholesale pricing on PWC decals, jet ski parts, and surface care products is built around volume turnover. Contact us for fleet quotes, multi-unit registration kits, and standing-order programs.
