The 3/4" heavy black barrel nipple is a adaptable fitting used for creating pipe connections in various industrial and plumbing applications. Here's a detailed breakdown of its specifications and functionalities:

Key Features

• Material: 

Malleable iron for superior strength and durability. Withstands high pressure and impact compared to standard steel nipples.

• Finish: 

The black iron finish offers a classic look and some level of corrosion resistance. 

Note: For environments prone to extreme moisture or harsh chemicals, consider galvanized nipples for enhanced protection.

• Size: 

Nominal diameter of 3/4 inches (approximately 19.05mm). This refers to the internal diameter of the pipe the nipple is designed to connect.

• Thread Type: 

Typically features Male (M) BSPT (British Standard Pipe Thread) threads on both ends. These tapered threads ensure a secure, leak-proof connection. Double-check thread compatibility with your specific pipes before purchase.

• Wall Thickness: 

"Heavy" refers to the increased wall thickness compared to standard nipples. This provides additional strength for applications with higher pressure or mechanical stress. Specific wall thickness details may vary depending on the manufacturer.


• Industrial Piping: 

Commonly used in air, gas, water, and oil lines within industrial settings due to its robust build.

• Plumbing Systems: 

Can be suitable for low-pressure water lines, irrigation systems, and compressed air applications within non-residential plumbing.

• Furniture Building: 

The industrial aesthetic of black iron can be used for creating furniture legs, handrails, or other structural elements. Important Note: Ensure structural calculations are done to confirm the nipple's suitability for weight-bearing applications.


• Pressure Rating: 

While "heavy" signifies increased strength, consult the manufacturer's specifications for the nipple's specific pressure rating. This will guide you to the maximum pressure the nipple can handle safely.

• Temperature Rating: 

Similarly, check the temperature rating to ensure the nipple fits the intended application's temperature range.

• Length: 

While this page focuses on the general specifications, 3/4" heavy black barrel nipples come in various lengths. Choose the length that precisely fits your project requirements.

• Thread Sealant: 

Apply an appropriate thread sealant during installation to ensure a leak-proof connection.
