Parker 61C-14 Compression Tube Nut Brass

Product Description

The PARKER 61C-14 is a brass compression tube nut designed for use in compression-style tube fittings across plumbing, HVAC, and fluid-handling systems. The nut threads onto a compression fitting body to secure tubing and create a leak-resistant mechanical seal without soldering or brazing. Constructed from brass, it offers good resistance to corrosion and compatibility with a wide range of fluids. The 61C-14 is rated for temperatures from -65 degrees F to 250 degrees F, making it suitable for both chilled-water and hot-water service applications. Licensed plumbers and HVAC technicians working with compression tube assemblies are the primary installers of this component.

The PARKER 61C-14 compression tube nut is used in residential and light commercial installations where compression fittings are specified. Common applications include potable water supply lines, refrigeration tubing, pneumatic lines, and hydronic systems. It is sold individually, allowing for single-unit replacement in the field without purchasing a full fitting assembly. Technicians typically reach for this nut when replacing a damaged or cross-threaded nut on an existing compression fitting body.

Key Features

• Brass construction provides corrosion resistance for wet and fluid-handling environments
• Compression end connection type — no soldering, brazing, or special tooling required
• Rated from -65 degrees F to 250 degrees F for broad service temperature coverage
• Sold in single-unit quantity for field replacement use
• Compatible with standard compression fitting bodies and ferrule assemblies

Compatibility

Designed as an OEM-style replacement compression tube nut for use with standard compression fitting assemblies in plumbing, HVAC, and fluid-handling applications.

Installation Notes

Installation of compression tube nuts is typically performed by licensed plumbers or HVAC technicians. Shut off and depressurize the line before disassembling any compression fitting. Hand-tighten the nut onto the fitting body first, then use an appropriately sized wrench to snug it — do not overtighten, as brass threads can strip or the ferrule can be deformed. Follow applicable IPC or local plumbing code requirements for the system type being serviced.
