They are commonly used in metal surface treating applications, plating solution lines, and other chemical process applications. Reinforced with layers of fiberglass, they have better strength and durability than any of our other pipe fittings for chemicals.

These PVDF fittings meet UL 94 V-0 for flame retardance, so they delay the spread of flames to valuable equipment. PVDF is comparable to Kynar, and has the chemical resistance to stand up to solvents and other harsh substances.

These fittings are an economical option for chemical waste systems. Fittings are ABS plastic, which has excellent strength and impact resistance and good chemical resistance.

Use these plastic fittings to connect gasoline fuel lines to machines and equipment. They have excellent corrosion resistance as well as high strength and impact resistance.

These Schedule 40 fittings are the industry standard for gravity-flow drain, waste, and vent (DWV) applications.

With thinner walls than Schedule 40 fittings, these are lighter in weight and have more space on the inside for high-flow applications, such as underground gravity-flow sewer and storm drainage lines. They are also known as SDR 35 fittings.

Polished to a 20 Ra finish, these fittings have an extra-smooth interior that prevents product buildup and inhibits bacteria growth.

Butt-weld fittings allow for a smooth, flush connection that provides maximum flow.

Use at pressures up to 4,300 psi.

For applications that require an extra level of cleanliness, these fittings are individually bagged to prevent contamination.

Individually bagged to prevent contamination, these fittings are suitable for applications that require a high level of cleanliness.

A single sleeve (ferrule) bites into tubing as you tighten the nut, creating a strong seal. The nut and sleeve are included.

A PTFE seal on the tube end of these fittings allows for an extra-strong connection in high-vibration applications.

An alternative to bolt-together fittings, these handle larger tube OD sizes and have higher vacuum ratings than quick-clamp fittings. Also known as ISO-K high-vacuum fittings, the clamps have claws that grab hold of fittings with flanged ends.

When cleanliness is crucial to your application, choose these fittings that are individually cleaned and bagged to prevent contamination.

The flared end of the fitting nests inside the fitting body, providing extra support to the tubing. Fittings are also known as inverted 45° flared fittings.
