3/4 inch PVC 90 Degree Insert Elbow Insert x Male

3/4 inch PVC 90° Insert Elbow – Barbed Fitting for Flexible Polyethylene Tubing

The 3/4 inch PVC 90° Insert Elbow is a barbed fitting used to facilitate directional changes in flexible polyethylene (PE) tubing, typically within irrigation, water service, or low-pressure fluid transfer systems. This elbow features a 90-degree bend and a combination of insert (barbed) and male thread ends for compatibility with standard poly pipe and threaded components.

Manufactured from durable, non-corrosive polyvinyl chloride (PVC), this fitting is engineered to resist chemical exposure and mechanical stress in outdoor or below-grade applications. The insert barb ensures a tight mechanical grip when clamped properly, while the male NPT thread allows for direct connection to female-threaded system components.

Product Features

• ✅ Material: PVC – lightweight, corrosion-resistant, and chemically stable.
• ✅ Connection: Insert (barbed) x Male NPT – allows secure transition between poly pipe and threaded fittings.
• ✅ Angle: 90 degrees – enables compact directional change in tight or confined piping runs.
• ✅ Size: 3/4 inch nominal – compatible with 3/4 inch ID polyethylene tubing and 3/4 inch female NPT threads.
• ✅ Clamping Required: Use with stainless steel hose clamps to ensure leak-free performance at insert end.

Applicable Standards

• Conforms to: ASTM D2609 (plastic insert fittings for use with PE tubing)
• Thread Type: ANSI/ASME B1.20.1 NPT threads
• Service Type: Cold water, irrigation, and non-pressurized drainage applications

Installation Notes

Insert the barbed end fully into polyethylene tubing using heat or lubrication if necessary. Secure with appropriately sized stainless steel clamps. The male NPT end should be installed using thread sealant approved for use with plastic fittings. Avoid overtightening to prevent thread deformation. Not for use in hot water or pressurized potable systems unless specified by the manufacturer and verified by local code.

Typical Applications

This fitting is commonly used in cold water distribution systems, agricultural irrigation lines, yard hydrant connections, and landscape drainage networks. It provides a 90-degree directional change in flexible tubing with a transition to threaded components such as valves, manifolds, or tees.

Material Insight

PVC insert fittings are widely specified for underground irrigation and water service lines due to their resistance to rust, ease of installation, and compatibility with polyethylene piping. When properly installed and clamped, they offer excellent mechanical reliability in demanding field conditions.

The 3/4 inch PVC 90° Insert Elbow delivers dependable performance in low-pressure fluid systems requiring directional flexibility and threaded integration. Designed to meet industry dimensional and material standards, it is a practical solution for contractors working with poly tubing assemblies.
