Striper Maintenance (Hoses, Washers, Pumps)

Striper Maintenance Parts: Hoses, Washers & Pumps

Line striping machines take a beating from paint, pressure, and constant vibration, and the hoses, washers, and pump-side components are usually the first things to wear out. This collection carries the small parts that keep suction and delivery systems sealed and flowing: the Newstripe Suction Hose Washer (sold in a 5-pack), the Suction Hose Sleeve, and the Suction Hose for EcoLiner LT & SP. For the delivery side, you'll find the Tank Outlet Hose and the Tank Outlet Hose for NewRider 5000, along with a Swivel Fitting Kit for connecting hose sections without leaks. Replacing these parts before they crack or split is far cheaper than losing a striping day to a blown fitting.

Wheels and Casters for Newstripe Line Stripers

Worn wheels are one of the most common reasons a striper starts laying an uneven or wandering line. We stock Newstripe wheels in 5", 8" plastic, 10", 15", 16", 18", and 410/350 sizes, so you can match the exact diameter used on your machine rather than guessing. For machines that steer or pivot, the Swivel Caster for NewRiders replaces a worn caster wheel assembly, and the Douglas Replacement Rollers cover a separate roller-based application. Before ordering, check the size stamped on your current wheel or the machine's parts diagram — Newstripe uses different wheel sizes across its striper and NewRider lineup, and sizes are not interchangeable between models.

Valves, Pulleys & Drive Components for NewRider and EcoLiner Machines

Beyond hoses and wheels, this collection covers the internal wear parts that keep drive systems and paint valves working correctly. For paint control, we carry the Valve Seat for Low Pressure (LP) Paint Applicators along with separate Valve Kits for Gas Powered EcoLiners and Battery Powered EcoLiners — buy the kit that matches your EcoLiner's power source. On the drive side, the NewRider 5000 uses a dedicated V-Idler Pulley and V-Belt (Final Drive), while the NewRider 1700 HPA has two versions of its Transaxle Pulley & Fan (Old/Rev A and New/Rev B), so confirm which revision your machine uses before ordering. A Transaxle Filter for NewRider and a Throttle Cable for 4600 SP Airless & EcoLiner SP round out the drivetrain and control parts.

Spray Guns, Applicator Arms & Small Hardware

For the spraying end of the machine, we stock a Spray Gun Mount Assembly, a Spray Gun Mount for 4250 Airless (Old Version), and a Spray Gun Assembly for EcoLiner Plus, plus the Spray Head and Spray Head Support for NewRiders. Sealing and support parts include the Tip Base Seal Kit, the Applicator Support Arm for Line Stripers, and the Trough Bellows & Clamps 3-Pack for AeroVent. Rounding out the catalog are the everyday hardware items that rarely get attention until they break: the Star Knob Replacement, Steering Wheel for NewRider, and U-Bolt with Nuts — all inexpensive fixes that keep a machine safe and adjustable.

Choosing the Right Replacement Part

Because 55 of the 56 items in this collection are Newstripe parts built for specific machines and model revisions, the fastest way to order correctly is to match the product title against your machine's model name — NewRider 1700 HPA, NewRider 5000, EcoLiner LT/SP/Plus, or 4250/4600 Airless. Where two versions exist, such as the old and new Transaxle Pulley & Fan for the 1700 HPA, compare your current part before purchasing a replacement. With prices spanning $4 to $272, you can budget for a full-season parts refresh (washers, seals, hoses) or a single larger component like a wheel or drive pulley as needed.
