Brass 3/8″ Compression Cap Fitting Pack of 25 Partner Machinery

Description

Product Overview

The Brass 3/8″ Compression Cap Fitting Pack of 25 from Partner Machinery is engineered for precision and durability in demanding plumbing applications. Each fitting is forged from high‑grade brass, a material celebrated for its corrosion resistance, strength, and long‑term stability in both residential and commercial environments. The fittings feature a 3/8″ compression interface, not an NPT thread, ensuring a secure, leak‑proof seal when paired with the included rubber gasket washer. Dimensions of each unit measure 3.55 x 3.08 x 1.26 inches and weigh just 7.84 ounces, making them easy to handle while still providing robust performance.

Designed with a compact cap style, these fittings are perfect for terminating the end of a compression line, protecting the pipe from contaminants, and providing a clean, finished look. The integrated sealing rubber gasket washer eliminates the need for additional sealing compounds, simplifying installation and reducing the risk of human error. With a best‑seller rank of #94,084 in Industrial & Scientific and #6 in Compression Cap Fittings, this product has earned a solid reputation among professionals and DIY enthusiasts alike.

Usage

These cap fittings are versatile enough to serve a wide range of plumbing scenarios. Whether you are installing a new sink shut‑off valve, repairing a toilet supply line, or configuring a dishwasher inlet, the 3/8″ compression design provides a reliable connection point that resists leaks under pressure. The fittings are also well‑suited for heating system loops, water heater supply lines, and under‑sink valve assemblies where space is limited and a clean termination is required.

Because the fittings are made from brass, they can tolerate both hot and cold water temperatures without degrading, making them ideal for use with hot‑water recirculation systems and radiant heating applications. The rubber gasket washer ensures a tight seal even when the pipe experiences slight movement or vibration, which is common in appliance installations. Installers appreciate the straightforward, tool‑free assembly: simply slide the fitting onto the pipe, position the gasket, and tighten the compression nut to the recommended torque.

For professional plumbers, the pack of 25 provides enough inventory to complete multiple projects without the need for frequent re‑ordering, improving workflow efficiency. DIY homeowners will find the clear labeling and consistent dimensions helpful when tackling bathroom or kitchen upgrades, as the fittings match standard 3/8″ compression tubing readily available at most hardware stores.

FAQ

What is the difference between a compression fitting and an NPT thread?

A compression fitting uses a tapered sleeve and a rubber gasket to create a seal when the nut is tightened, while an NPT (National Pipe Thread) fitting relies on threaded connections and sealant tape. The 3/8″ size in this product refers to the compression interface, not an NPT thread, so it will not mate with NPT‑rated components.

Can these fittings be used with both hot and cold water lines?

Yes. The brass material is rated for a wide temperature range, making the fittings suitable for hot‑water recirculation, water heater supply lines, and cold‑water distribution without risk of degradation.

Do I need any special tools to install the cap fittings?

No special tools are required. A standard wrench or adjustable pliers is sufficient to tighten the compression nut to the recommended torque. The included rubber gasket washer eliminates the need for additional sealants.

How many fittings are included in the pack?

The package contains 25 individual brass 3/8″ compression cap fittings, each with its own rubber gasket washer, providing ample inventory for multiple projects.
