Hydraulic Adapter Fitting with Restrictor Orifice – 3/8″ NPTF to NPSM Swivel

Description

When you need precise flow control in your hydraulic system, this adapter fitting with built-in restrictor orifice gives you exactly that. Whether you’re dealing with a hydraulic cylinder that moves too fast, a loader that jerks when you operate it, or any situation where you need to dial back the flow rate, this little fitting can make all the difference in how smoothly your equipment operates.

What You’re Getting

• Built-in 1/32″ restrictor orifice that controls flow rate for smoother operation
• Swivel female end rotates freely to eliminate binding and make hookup easier
• 7/8″ hex on both ends gives you plenty of grip for installation with standard wrenches
• 4000 PSI operating pressure rating handles the demands of high-pressure hydraulic systems
• Direct thread conversion from male NPTF to female NPSM without adapters or multiple fittings

Built for Real Farm Work

This adapter is perfect for hydraulic systems on tractors, loaders, and implements where you need to slow down cylinder movement or reduce flow rates. The restrictor orifice is especially helpful when you’re working with hydraulic cylinders that need more controlled movement – like dump beds that need to lower slowly, or loader arms that work better with smoother operation rather than quick jerky movements.

Made to Last

The AgSmart construction means this fitting is built to handle the vibration, pressure changes, and tough conditions that come with farm equipment. The swivel design reduces stress on hydraulic lines by allowing the connection to move freely, which helps prevent leaks and extends the life of your hoses and fittings.

Installation Notes

The restrictor orifice is permanent and sized at 1/32″, so make sure that flow rate works for your application before installing. Use appropriate thread sealant on the male NPTF threads, but remember the female NPSM end doesn’t need sealant since it relies on an O-ring seal. The swivel feature means you can orient your hydraulic line exactly where it needs to go without twisting the hose.
