Male 1/4 NPT thread brass steel hexagonal Compressed air pneumatic plug-in nipples

Overview

Engineered for reliable performance in pneumatic systems, the Male 1/4 NPT Thread Brass Steel Hexagonal Compressed Air Pneumatic Plug-in Nipples are precision-manufactured connectors designed to establish secure, leak-free connections in air compression setups. Constructed with a durable brass body and steel hexagonal nut, these nipples combine corrosion resistance with mechanical strength, ensuring long-lasting use in industrial, commercial, and DIY applications. The 1/4 NPT (National Pipe Thread) male thread conforms to international standards, providing compatibility with a wide range of fittings, hoses, and equipment. The plug-in design allows for quick installation and removal, making them ideal for systems requiring frequent adjustments or maintenance. Whether used in automotive workshops, manufacturing plants, or air-powered tools, these nipples deliver consistent performance under varying pressure conditions, ensuring optimal airflow and system efficiency.

Features

1. Dual-Material Construction: The nipple features a brass body for excellent corrosion resistance in wet and corrosive environments, paired with a steel hexagonal nut for enhanced torque resistance during installation. This combination ensures durability without compromising on weight or flexibility.

2. Standardized NPT Thread: The 1/4 NPT male thread adheres to ASME B1.20.1 standards, providing a tapered, leak-proof seal when paired with compatible female fittings. The thread pitch (18 threads per inch) ensures easy alignment and secure tightening, minimizing the risk of air leaks.

3. Hexagonal Nut Design: The steel hexagonal nut allows for easy tightening and loosening with standard wrenches, reducing installation time and effort. The nut’s surface is treated with a rust-resistant coating, extending the nipple’s lifespan in high-moisture environments.

4. High-Pressure Compatibility: Rated for working pressures up to 200 PSI (pounds per square inch), these nipples maintain structural integrity and sealing performance under moderate to high pneumatic loads, making them suitable for demanding industrial applications.

5. Versatile Plug-in Style: The plug-in end is designed to fit seamlessly with standard pneumatic hoses (6mm to 8mm inner diameter), allowing for quick disconnects and reconnects without tools. This feature is particularly useful for mobile equipment or temporary setups.

Application

• Pneumatic Tool Systems: Ideal for connecting air compressors to impact wrenches, drills, sanders, and spray guns in automotive repair shops and manufacturing facilities.

• Industrial Automation: Used in conveyor systems, robotic arms, and pneumatic cylinders to ensure reliable air supply for automated processes.

• DIY and Workshop Setups: Suitable for home garage air lines, woodworking machinery, and small-scale compressed air applications where ease of installation is critical.

• Marine and Outdoor Equipment: The corrosion-resistant brass body makes these nipples suitable for marine air systems, outdoor power tools, and equipment exposed to harsh weather conditions.

FAQ

Q: What is the difference between NPT and BSP threads?

A: NPT (National Pipe Thread) is a tapered thread used in North America, while BSP (British Standard Pipe) can be parallel (BSPP) or tapered (BSPT). These nipples use 1/4 NPT, which requires Teflon tape or sealant for a watertight/airtight seal, unlike BSPP that uses O-rings.

Q: Can these nipples be used with water or hydraulic systems?

A: While primarily designed for compressed air, the brass construction allows limited use with water systems (non-potable). For hydraulic applications, consider our steel hydraulic nipples rated for higher pressures.

Q: What is the temperature range for these nipples?

A: They perform optimally between -20°C and 60°C (-4°F to 140°F). Prolonged exposure to temperatures outside this range may affect the sealant’s effectiveness.

Q: Do I need a specific tool to install the plug-in end?

A: No, the plug-in end is designed for hand insertion into compatible hoses. Ensure the hose is fully seated until it clicks to prevent accidental disconnection.

Q: Are these nipples compliant with OSHA standards for workplace safety?

A: Yes, they meet OSHA requirements for pneumatic system components when installed correctly with appropriate pressure ratings and safety measures.
