Safety Information
Always observe basic safety precautions when working with plumbing components. Failure to follow these instructions could result in property damage or personal injury.
- Turn off water supply: Before beginning any plumbing work, ensure the main water supply to the area is completely shut off.
- Wear appropriate personal protective equipment (PPE): This includes safety glasses and gloves.
- Use correct tools: Employ appropriate wrenches and tools for tightening fittings.
- Do not overtighten: Excessive force can damage threads on the nipple or mating fittings, leading to leaks.
- Check for leaks: After installation, slowly restore water pressure and carefully inspect all connections for leaks.
Product Overview
The Brasscraft 112-04-R is a 1/4-inch NPT (National Pipe Taper) close brass nipple. A close nipple is a pipe fitting that is very short, with threads running along its entire length, allowing two other fittings to be connected as closely as possible. It is constructed from durable brass, suitable for various plumbing applications.

Installation Instructions
Follow these steps for proper installation of the brass nipple:
- Prepare threads: Ensure that the threads on both the nipple and the mating female fittings are clean and free from debris.
- Apply thread sealant: Apply an appropriate amount of PTFE (Teflon) tape or pipe thread compound to the male threads of the brass nipple. Wrap PTFE tape clockwise around the threads, typically 2-3 wraps.
- Hand tighten: Carefully thread the nipple into the first female fitting by hand until it is finger-tight. Ensure it is not cross-threaded.
- Wrench tighten: Using an appropriate wrench, tighten the nipple an additional 1 to 2 turns past finger-tight. Avoid excessive force to prevent stripping threads or cracking fittings.
- Connect second fitting: Repeat steps 3 and 4 for the second female fitting, connecting it to the other end of the brass nipple.
- Test for leaks: Slowly turn on the water supply and carefully inspect all connections for any signs of leakage. If leaks are detected, turn off the water, slightly tighten the connection, and re-test. If leaks persist, disassemble, reapply sealant, and reassemble.
Usage
The Brasscraft 112-04-R 1/4-inch Close Brass Nipple is designed to create a secure, leak-free connection between two female NPT threaded components in a plumbing system.

Maintenance
Brass nipples generally require minimal maintenance. However, periodic inspection is recommended to ensure system integrity.
- Visual Inspection: Periodically check the nipple and surrounding connections for any signs of corrosion, leaks, or physical damage.
- Leak Detection: If a leak is suspected, follow the troubleshooting steps outlined in this manual.
- Replacement: If the nipple shows signs of significant corrosion, cracking, or damage, it should be replaced immediately by a qualified professional.
Troubleshooting
Most issues related to pipe nipples involve leaks. Use the following guide to address common problems:
| Problem | Possible Cause | Solution |
|---|---|---|
| Leak at connection point | Insufficient thread sealant, loose connection, damaged threads, cross-threading. | Turn off water supply. Disassemble the connection. Inspect threads for damage. Clean threads. Reapply thread sealant (PTFE tape or compound). Reassemble and tighten appropriately. Test for leaks. If threads are damaged, replace the nipple or fitting. |
| Nipple will not thread into fitting | Cross-threading, incorrect thread size, debris in threads. | Ensure correct thread size (NPT 1/4-inch). Clear any debris from threads. Carefully align and attempt to hand-thread again. Do not force. If cross-threaded, threads may be damaged and require replacement. |
