1-1/4 inch x Close Brass Nipple

1-1/4" x Close Brass Nipple – Threaded Connector for High-Integrity Systems

The 1-1/4" x Close Brass Nipple is designed for secure, threaded connections in pressurized water, air, or non-corrosive gas systems. Fabricated from lead-free brass, this fitting offers corrosion resistance and mechanical durability in both residential and commercial piping assemblies. Its short overall length ("close") allows for compact installations where space is limited.

Built for Demanding Conditions

Brass nipples are specified where precision threading and resistance to dezincification are essential. This close nipple supports pipe-to-fitting or pipe-to-valve connections where alignment and tight seal integrity are critical. Key advantages include:

• ✅ Machined NPT Threads – Conforms to ANSI/ASME B1.20.1 for tapered pipe threads, enabling leak-resistant joints.
• ✅ Lead-Free Brass Alloy – Complies with NSF/ANSI 61 and 372 standards for use in potable water systems.
• ✅ Pressure Rated – Suitable for high-pressure installations when used within system limitations and with appropriate sealant.
• ✅ Corrosion-Resistant – Suitable for applications exposed to intermittent moisture or low-corrosive fluids.

Specifications

• Nominal Size: 1-1/4" NPT x Close
• Material: Lead-Free Brass
• Connection Type: Male Threaded x Male Threaded (NPT)
• Compliance: NSF/ANSI 61, NSF/ANSI 372, Lead-Free Code Requirements

Installation Requirements

Install using standard pipe wrenches and appropriate joint compound or PTFE tape for a sealed connection. Do not over-torque. Verify compatibility with system media and ensure alignment with local plumbing codes. Intended for use by licensed professionals in accordance with standard installation practices.

Typical Applications

Commonly used in pump connections, water heater tie-ins, pressure vessel terminations, and transitional piping where space constraints dictate the need for close-length nipples. Compatible with brass, bronze, CPVC, and approved steel pipe systems.

Material Insight

Brass is widely used in plumbing and mechanical systems due to its balance of strength, workability, and corrosion resistance. Lead-free formulations ensure compliance with U.S. drinking water legislation in all jurisdictions.

The 1-1/4" x Close Brass Nipple delivers high-performance connection reliability in mission-critical applications. It is a trusted choice for professional installations where mechanical strength, regulatory compliance, and compact design are non-negotiable.
