Pipe and Pipe Fittings

FM-Approved Low-Pressure
Cast Iron Threaded Pipe Fittings

Low-Pressure Press-Connect
Steel Unthreaded Pipe Fittings

Crimp these fittings onto steel pipe to form a tightly sealed connection that’s faster than threading or welding and doesn’t require heat.

Iron and Steel Pipe Fittings with Flanged Ends

Bolt the flanged end of these fittings to another same-size flange, pump, or valve with a gasket to create an access point in a pipe line.

Grooved-End Iron Pipe Fittings

The grooved ends on these iron fittings connect to pipe with a clamp to easily install piping systems.

Flame-Retardant PVDF 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.

Gravity-Flow CPVC Pipe Fittings
for Corrosive Chemical Waste

These fittings are NSF certified for use in corrosive waste gravity-flow systems. Made of CPVC, they have better chemical resistance than ABS plastic gravity-flow fittings and can stand up to highly-corrosive acids and other harsh substances.

Fire-Fighting Hose Fittings

Connect these fittings to fire hydrants and washdown equipment.

Rocker-Lug Fire-Fighting Hose Fittings

The rocker lugs on these fittings allow for easy gripping, so you can quickly connect to fire hydrants and washdown equipment.

Pin-Lug Fire-Fighting Hose Fittings

The pin lugs on these fittings allow for easy gripping, so you can quickly connect to fire hydrants and washdown equipment.

Diverting Valves with Fire-Fighting Hose Fittings

Control the flow of water in two directions from a single source—these diverting valves have two balls and handles for independent operation of each outlet. Use with fire-fighting hose.

Electrical

Reducers for Flexible Plastic Conduit

Connect different sizes of conduit.

Multiple-Voltage DIN-Rail Power Supplies

Power multiple devices with different voltages at the same time—these power supplies take AC voltage and convert it into several DC voltages at once.

Filtered D-Sub Connectors

With a ferrite filter block surrounding their contacts, these connectors control and reduce the electromagnetic (EMI) and radio frequency (RFI) interference traveling through them.

Harsh-Environment EMI-Filtering IEC Connectors

Power electronics in damp environments while protecting them from electromagnetic interference.

EMI-Filtering IEC Connectors with Power Switch

With a built-in switch, these connectors run power to appliances, power supplies, and other electronic devices while also filtering damaging EMI (electromagnetic interference).

EMI-Filtering IEC Connectors

Bring power into electronic devices while protecting them from harmful electromagnetic interference (EMI).

EMI-Filtering IEC Connectors
with Integrated Power Supply

Change AC voltage to DC voltage and bring power to electronic devices while protecting them from harmful electromagnetic interference (EMI).

Sound Insulation

Vibration Damping Sheets

Install these adhesive-back sheets to reduce noise from vibrating surfaces, such as duct and equipment housings.

Contoured Sound-Absorbing Sheets

Also known as egg crate, these sheets have peaks and valleys that absorb more sound at higher frequencies than flat-surface sheets. Use them to quiet noisy areas and line machine enclosures. Sheets are made of humidity-resistant polyurethane foam.

Sound-Absorbing Sheets

Use these sheets to quiet noisy areas and line machine enclosures. They’re made of humidity-resistant polyurethane foam and have a smooth, easy-to-clean facing.

Heat-Reflecting Sound-Absorbing Sheets

The foil facing reflects heat. Use these sheets to quiet noisy areas and line machine enclosures. They’re made of humidity-resistant polyurethane foam.

Oil-Resistant Sound-Absorbing Sheets

Either a urethane or polyester coating protects these humidity-resistant polyurethane foam sheets from oil exposure. Use them to quiet noisy areas and line machine enclosures.

Flame-Retardant Rigid Sound-Absorbing Sheets

Made of melamine foam, these sheets meet UL 94 V-0 for flame retardance and ASTM E84 5/20 for flame and smoke. Use them to quiet noisy areas and line machine enclosures. Sheets are peaked on one side for more sound-absorbing area than flat-surface sheets.

Easy-to-Hang Rigid Sound-Absorbing Sheets

Furnished with two hangers for easy mounting around your facility, these sheets quiet noisy areas. Made of melamine foam, they are peaked on both sides for good sound absorption in large open spaces.

Rigid Ultra-Sound-Absorbing Sheets

The best sound absorbers of all our rigid sheets, use to quiet noisy areas in your facility. They're peaked on one side for more sound-absorbing area than flat sheets. Made of melamine, they have an acrylic resin finish that resists dust and dirt and wipes clean.
