How to Measure Threaded Pipe Size

Right-Angle Flow Rectangular Manifolds

Distribute air or fluid to multiple locations from a single supply source with these manifolds. They are also known as headers.

Dual-Section Right-Angle
Flow Rectangular Manifolds

These manifolds have two separate sections inside, so you can run two different substances through them without worrying about them intermixing. Also known as headers.

Cleaned-and-Bagged Right-Angle
Flow Rectangular Manifolds

Designed for ultra-clean environments, these manifolds are cleaned, dried, and vacuum sealed in plastic to prevent dirt and moisture from contaminating the inside. Use them to distribute air or fluid to multiple locations from a single supply source. Also known as headers.

Straight-Flow Rectangular Manifolds

Unlike other manifolds, which have an inlet on either end, these have one inlet on the opposite side from the outlets. This design allows air or fluid to follow a straight path, improving flow through your system. Also known as headers.

Low-Profile Hex Manifolds

When you’re short on vertical space, these manifolds are a good fit—they have outlets on the side instead of on top, so they have a lower profile than rectangular manifolds. Use them to distribute air or fluid to five locations from a single supply source.

Low-Profile Square Manifolds

With outlets on the side instead of on top, these manifolds have a lower profile than rectangular manifolds and fit well in cramped spaces. Use them to distribute air or fluid to three locations from a single supply source.

Round Manifolds for Hose Lines

Mount these manifolds on the end of a hose line to distribute air, water, or hydraulic fluid to three locations from a single supply source.

Right-Angle Flow Junction Blocks

These junction blocks have threaded holes that allow air or fluid to flow at a 90° angle through the block. Use them to organize and separate multiple lines in your system.

Tubing and Tube Fittings

Moisture-Resistant Push-to-Connect
Tube Fittings for Air and Water

These fittings won’t absorb moisture, so they’re good for water and high-humidity air applications.

Push-to-Connect Tube Fittings for Air

Yor-Lok Fittings for Stainless Steel Tubing

Use these fittings at pressures up to 9,700 psi. Also known as instrumentation fittings, they are made to tight tolerances for use in high-precision applications. They are compatible with Swagelok®, Let-Lok, and Parker A-Lok fittings.

Solder-Connect Fittings for Copper Tubing

Solder these fittings to tubing for a permanent, leak-tight connection. They are also known as sweat fittings.

Quick-Disconnect Hose Couplings for Air and Water

Industrial Quick-Disconnect Hose Couplings for Air

The industry standard for quick-disconnect couplings, these are also known as industrial interchange couplings. Compatible with Industrial-shape plugs and sockets.

ARO Quick-Disconnect Hose Couplings for Air

Compatible with ARO-shape plugs and sockets.

1/2" Snap-Loc Coolant Hose

NFPA Valve-Mounting Blocks

NFPA valve-mounting blocks have standardized valve mounting patterns to keep hydraulic lines compact and organized.

Threaded Precision Flow-Adjustment Valves

High-Pressure Threaded Precision
Flow-Adjustment Manifolds

Often attached to differential pressure gauges to measure liquid level in tanks, these manifolds have two isolation valves with a pressure-equalizing valve between them. To isolate your differential pressure gauge for maintenance or calibration, shut off flow on both sides and equalize pressure in the manifold. They are rated for at least 6,000 psi. Use with water, oil, air, and inert gas.

High-Pressure Threaded Precision
Flow-Adjustment Valves with Vent Ports

Also known as block and bleed valves, these have two vent ports to isolate pressure gauges, switches, and other components in high-pressure systems for maintenance, calibration, and sampling without interrupting the process. They are rated for up to 10,000 psi. Use with water, oil, air, and inert gas. Turn the handle to adjust flow in small increments for metering, sampling, and other applications requiring fine flow control.

Threaded Precision Flow-Adjustment
Valves with Gauge Ports

With a gauge port on each side of these valves, you can install two different pieces of instrumentation equipment to simultaneously monitor multiple media properties without interrupting flow. Use with water, oil, air, and inert gas. Turn the handle to adjust flow in small increments for metering, sampling, and other applications requiring fine flow control.

Threaded Precision Flow-Adjustment
Valves with Vent Port

Also known as block and bleed valves, these have a vent port that allows you to remove instrumentation equipment attached to the valve without depressurizing your line. Turn the handle to shut off flow and remove the vent port plug to drain liquid trapped in the valve. Use them with water, oil, air, and inert gas. These valves adjust flow in small increments for metering, sampling, and other applications requiring fine flow control.

T-Slotted Framing Manifolds

Distribute compressed air, hydraulic fluid, or water from a single supply to multiple locations.
