Description
The Merit Brass 161-4012-001 3/4″ Close Schedule 40 Stainless Steel Nipple is engineered for dependable performance in demanding agricultural irrigation and manure transfer applications. Constructed from premium 304/304L stainless steel, this close nipple provides maximum corrosion resistance while maintaining structural integrity under pressure and vibration common in farm operations.
A “close nipple” design means there is little to no exposed pipe between the threaded ends, making it ideal for compact installations where space is limited or leak points must be minimized. This fitting is commonly used to join two female threaded components such as valves, couplers, manifolds, filters, or pumps.
Features & Benefits
Corrosion Resistance
304/304L stainless steel resists rust, scaling, and chemical breakdown caused by fertilizers, manure slurry, and irrigation chemicals. This significantly extends service life compared to brass fittings.
Strength and Durability
Schedule 40 wall thickness provides reliable pressure handling and structural strength for both irrigation water delivery and nutrient or manure transfer systems.
Sanitary and Clean Flow Characteristics
Stainless steel offers smooth interior surfaces that help reduce buildup, scaling, and contamination risks.
Compact Close Nipple Design
Allows tight installation between components while minimizing potential leak points.
Low Maintenance
Stainless fittings typically require less frequent replacement, reducing downtime during irrigation or manure application seasons.
Pros
• Excellent corrosion resistance in harsh agricultural environments
• Longer service life compared to brass or plated steel
• Higher strength and pressure durability
• Improved resistance to chemical fertilizers and manure acids
• Reduced maintenance and replacement frequency
Cons
• Higher initial cost than brass fittings
• Stainless steel can gall if over-tightened without thread lubricant
• 304 stainless may not be ideal for extremely high chloride or salt exposure (316 stainless may be preferred in coastal or heavy salt environments)
Standard Agricultural Uses
• Connecting valves, manifolds, and regulators in irrigation systems
• Drip irrigation mainline and filtration connections
• Manure drag hose and slurry transfer plumbing
• Pump discharge and suction plumbing
• Fertigation and chemical injection assemblies
• Water transfer and livestock watering systems
