Smith Performance Sprayers Gasket Repair Kit for B&G 1-Gallon Stainless with Extenda-Ban Valve — OEM-fit, Viton & Teflon Seals

Complete gasket and valve repair kit designed to restore one B&G® 1-gallon stainless steel sprayer with Extenda-Ban® next-generation valve to OEM-level performance.

This Smith Performance Sprayers replacement kit is a direct-fit alternative to the B&G GD-124 repair set and contains every internal seal and spring needed to refurbish a single 1-gallon stainless sprayer equipped with Extenda-Ban valves. All components — from the purple polypropylene plunger cup to Teflon packing washers and a brass soft-seat gasket with Viton O-ring — are manufactured to meet or exceed OEM specifications and are supplied with an installation guide and lubrication tube for an efficient repair.

What parts come in the kit and why do they matter?

The kit includes a hose gasket, bottle gasket, check valve, pump tube gasket, plunger gasket, valve spring, pump lock spring, plunger, and lubrication tube. Each part addresses common wear points that cause leaks, pressure loss, or sticky valve action in older sprayers.

• Purple plunger cup: durable high-grade polypropylene for repeated sealing cycles.
• Teflon packing washers: low-friction operation and chemical resistance.
• Brass soft-seat with Viton O-ring: secure sealing and improved chemical compatibility.
• 303 stainless steel springs and plunger: corrosion resistance for longevity.

How do I know this kit fits my B&G sprayer model?

This replacement set is made to be compatible with many B&G models that use Extenda-Ban® valves. Refer to the included PDF compatibility chart for exact cross-references—models such as N74-CC, N124-CC, N524-CC and multiple -S and -CC-18/-24 variants are covered.

• Cross-reference chart included in the product PDF for precise verification.
• Designed as an alternative to OEM GD-124 repair kit.
• Made for 1-gallon stainless sprayers with Extenda-Ban valves.

How difficult is installation and what tools are required?

Installation is intended to be straightforward for anyone comfortable with basic sprayer maintenance. The kit includes clear, step-by-step instructions (PDF) and a small lubrication tube; typical installation requires only basic hand tools and about 15–30 minutes.

• PDF instructions provide a stepwise guide for disassembly and reassembly.
• No specialized tools required—common screwdrivers and pliers usually suffice.
• Lubrication tube included to ensure correct O-ring and gasket seating.

What materials are used and how do they affect durability?

Components are selected for chemical resistance and mechanical longevity: Viton O-rings for broad chemical compatibility, Teflon washers for low friction, polypropylene plunger cup for wear resistance, and 303 stainless steel for spring and plunger strength. These materials reduce leak risk and extend service intervals compared with worn OEM parts.

• Viton O-rings: resistant to many common agricultural and horticultural solutions.
• Teflon washers: minimize wear and sticking in the pump mechanism.
• 303 stainless steel parts: resist corrosion in humid or chemical-exposed environments.

Who this kit is for: This Smith Performance Sprayers gasket repair kit is aimed at professional applicators, maintenance technicians, landscapers, and DIY users who own a B&G® 1-gallon stainless sprayer with Extenda-Ban® valve and want a reliable, OEM-grade repair without purchasing a full replacement sprayer. It’s especially useful for shops and service crews that perform periodic maintenance and want high-quality replacement components manufactured in the USA.
