Pipe Fittings

With so many different pipe fitting sizes, materials of construction, and available configurations, it can be challenging to determine which fitting is the best choice for your pneumatic system. Polyconn is your go-to supplier of high-quality, durable, and cost-effective pipe fittings. We can source any stainless steel, brass, or nickel-plated brass fitting you need—no matter how hard it is to find.


Stainless Steel Pipe Fittings

Our available stainless steel pipe fittings are all constructed of 304 stainless steel. They are suitable for use with compressed air, non-potable water, oil, natural gas, and steam. Maximum pressure occurs at 150 PSI at 72°F. They are ideal for low-pressure applications.

When to Choose Stainless Steel

Many advantages come from choosing stainless steel pipe fittings for your application. Stainless steel is strong, durable, and resistant to corrosion, making it an excellent choice for environments with harsh conditions. It has a high temperature tolerance and stands up to UV radiation. It also has an attractive appearance, increasing the aesthetic appeal for visible pneumatic systems.

Brass & Nickel-Plated Brass NPT Pipe Fittings

We stock a variety of brass and nickel-plated brass pipe fittings which meet SAE, ASME, and ASA requirements. They are designed for low and medium pressure connections and are commonly used to move non-potable water, grease, fuels, and other substances. Brass and nickel-plated fittings operate at pressures up to 1000 PSI and in a temperature range from -68° to +250°F. They feature a fair resistance to vibration and pipe movement.

When to Choose Brass or Nickel-Plated Brass (NPT)

Brass and nickel-plated brass (NPT) pipe fittings feature good corrosion resistance and are easy to install. When thread sealant is applied, a tight seal is easily created. These pipe fittings are versatile, durable, and tolerate high temperatures with ease.
Brass is malleable, making it a good fit for when pipe fittings will require bending or shaping. Nickel-plated brass increases the component’s resistance to corrosion both inside and outside of the fitting.

What are NPT Pipe Fittings?

National Pipe Tapered (NPT) fittings designed to seal pipes to transfer fluid and gas. NPT pipe fittings are available in most markets and in many shapes, sizes, materials, and configurations, and they are often easy to install. However, overtightening can cause port expansion or cracking, and most NPT pipe fittings are unsuitable for high-pressure applications.
