Restore reliable outdoor water access with the E-cowlboy 850SB Parts Kit

The 850SB Parts Kit is designed to help you renew frost-proof yard hydrants without replacing the entire unit. It’s compatible with a wide range of Simmons models, including 800LF–818LF Deluxe Frost-Proof Yard Hydrants, 820LF–828LF Series with stainless pipe and pump rod, 800SB–808SB Deluxe hydrants, 4800LF–4808LF Premier models, 5800LF–5806LF Designer Series, and 6800LF–6806LF Sanitary Series. If you own multiple hydrant types, this kit offers a versatile, OEM-aligned set of parts that can help you regain smooth operation and a tighter seal, even after years of exposure to moisture and cold weather.

What makes this kit worth considering

• Direct OEM replacement compatibility: It’s designed to mirror the original components for several OEM part numbers, offering a straightforward rebuild option instead of full hydrant replacement.
• Full rebuild in one kit: With eight essential internal components, you can refresh the critical working parts and restore control over flow and pressure.
• Durable materials for outdoor use: Brass parts resist corrosion, stainless steel offers strength, and Buna-N O-rings provide reliable resistance to oil, water, and temperature changes.

Inside the 8-piece kit

• Plunger (1) and Buna-N O-rings (2) for a tight seal and smooth action
• Brass packing nut (1) and brass connector (1) for secure assembly
• Brass links (2) to restore linkage movement
• Stainless steel lock nut (1) and stainless fulcrum bolt (1) for durable fastening

Ease of installation

Designed for DIY repair, this kit lets you replace worn internal parts without special tools. In many cases, a standard wrench and screwdriver are enough to complete the rebuild. The process focuses on reseating the new plunger, reassembling linkages, and renewing seals to help you regain dependable operation.

When to consider this kit

• Leaks around the hydrant base or slow/shaky opening and closing
• Hydrants that are difficult to shut off or stay in a fixed position
• Equipment used in barns, gardens, driveways, or other outdoor spaces that require steady water access

Durability and warranty

Constructed from brass, stainless steel, and Buna-N rubber, the components are built for outdoor wear and temperature variation. The kit includes a 12-month warranty against quality issues, plus a 30-day money-back guarantee for peace of mind. If you need assistance, our support team is ready to help with installation questions or compatibility concerns.

With the 850SB Parts Kit, property owners may enjoy improved hydrant performance, reduced moisture-related wear, and the convenience of handling routine maintenance in-house. Keep a spare kit handy for winter-ready repairs, and you’ll have a practical, ready-to-use solution at your fingertips.
