How to Identify and Measure Fittings

Pipe size is an industry designation, not the actual size. View information about how to measure threaded and unthreaded pipe and pipe fittings.

Trap small particles in tubing or pipe to ensure samples are contaminant free for testing applications. Filters protect sensitive process equipment from damage caused by debris.

Clear filters allow you to monitor dirt accumulation.

Filters with a filter-change indicator change from white to red when they need to be replaced.

Plastic filters offer excellent chemical resistance. Brass filters have good corrosion resistance.

High-Pressure Inline Filters

Remove small particles in high-pressure applications up to 5,000 psi to protect sensitive equipment, such as hydraulic controls. Without adding bulk to your line, inline filters act as a secondary defense to trap particles that make it past your intake filter.

Brass filters have good corrosion resistance. Stainless steel filters have excellent corrosion resistance.

Filters with an access port let you install a new filter element without replacing the entire unit or removing it from your line. However, they take up slightly more space than filters without access ports.

High-Vacuum Inline Filters

Capture oil, oil vapor, and other contaminants from your pump to prevent them from spreading into your high-vacuum system with these filters. When it's time to replace the filter element, you don't need tools to access it; undo the quick-release clamp to open the filter body. Filters have a drain port to remove collected oil.

Filters with quick-clamp connections (also known as KF, NW, and QF fittings) require a quick clamp and a ring (both sold separately) for each connection.

Filters with claw-clamp connections (also known as ISO-K fittings) will connect to larger components than filters with quick-clamp connections. Use four claw clamps and a ring (all sold separately) to secure each connection. Double-claw clamps attach to the grooves on the fittings. Single-claw clamps have a clamp on one end and an exposed bolt on the other. Thread the bolt-end directly into the body of pumps, valves, or other high-vacuum components.

Vacuum-Rated Air-Intake Filters

Typically used on vacuum pumps, these filters ensure that clean air is going in and coming out of your system. Install them on the inlet to stop dust from entering your equipment.

Replacement elements are sold separately. HEPA elements have greater efficiency for high-purity applications, but they reduce the maximum flow rate of your filter. Polyester and fiberglass are more durable than paper.

High-Vacuum Air-Intake Filters

Install these filters between your high-vacuum chamber and the inlet of your pump to remove dust, water vapor, and other contaminants from the system and protect the pump. Commonly used in vacuum-furnace and coating applications, they have a polyester filter element that traps particles as small as 5 microns. All filters have been helium-leak tested to ensure quality. When the filter element becomes clogged, you can replace it.

Quick-clamp connections are also known as KF, QF, and NW connections; they require a ring and quick clamp (sold separately) to complete the connection.

Claw-clamp connections are also known as ISO-K connections; use a ring and multiple claw clamps (sold separately) to secure. Double-claw clamps attach to the grooves on the fittings. Single-claw clamps have a clamp on one end and an exposed bolt on the other. Thread the bolt-end directly into the body of pumps, valves, or other high-vacuum components.

Threaded On/Off Valves with Easy-Access Strainer

A built-in strainer traps debris and allows you to replace the screen without disconnecting your pipeline. These valves have a T-handle or lever that resists accidental movement when snagged or bumped. They are full port, so they do not restrict flow.

Nickel-plated brass valves are more corrosion resistant than plain brass valves.
