Couplings & Fittings

Cam and groove fittings

A cam and groove coupling, also called a "camlock" fitting, is a form of hose coupling popular because it is a simple and reliable means of connecting and disconnecting quickly and without tools.

Pin-lug couplings

Also called "suction hose couplings," these are threaded couplings used for suction or discharge of water or other fluids.

Combination hose nipples

Combination hose nipples are used in a variety of fluid applications. They are available in unplated steel, plated steel, polypropylene, and stainless steel.

Universal air couplings

Also called "Chicago," "CP," or "Crow's Foot" couplings. Used to connect air lines from compressors or other air sources to all types of pneumatic tools and equipment. All 2-lug head connections are of one size for easy interchange.

Ground joint couplings

An all-purpose coupling, the female ground joint consists of a MALE STEM, WING NUT and FEMALE SPUD. The female spud has NPT threads to accept the NPT threads of a rigid connection or male NPT nipple. Widely used for air, water or steam, the ground joint is secured with an interlocking clamp or ferrule.

Sandblast couplings

There are three active sandblast system couplings: NOZZLE HOLDERS that accept the male threaded end of a sandblast nozzle, the THREADED POT END that is connected to the combination air and abrasive mix from the sandblast pot, and HOSE ENDS that are used to make hose-to-hose connections or hose-to-blast pot connections.

Hose menders

Hose menders repair hoses up to and including IDs of 12". After cutting out the damaged hose portion, insert each end of the mender (shanks) into the remaining good ends of the hose.

Push-on fittings

Brass Push-On Fittings are specially manufactured for use with push-on hoses in low pressure applications. No clamp or ferrule is required if properly inserted.

Brass threaded hose fittings

Recommended for low pressure air and water applications. Attachable with ferrules or hose clamps. Also available in stainless steel.

Garden hose fittings

Brass fittings with standard garden hose thread (GHT) for general purpose use. The female end swivels for easy connection. Many adapters are available for making the connection to the pipe thread.

Locking lever couplings

For use with water pumps and irrigation. Locking lever fittings are galvanized quick couplings, each with a double-pin locking lever for smooth closing. Not recommended for use with toxic chemicals. O-Ring is included in all female parts.

Quick detachable couplers

All engagements available.

Material Guide

Gasket Materials

GREEN GENERAL PURPOSE GASKET SHEET

Excellent gasket material with good chemical and petroleum resistance. Excellent sealability in oil, gasoline, mild chemical, water, and other fluid applications. See our commercial flange gasket chart for information on standard gasket sizes.

COMPRESSED GASKET SHEET with NITRILE BINDER

A premium sheet constructed from aramid fibers and a Nitrile binder. This material serves in water, aliphatic hydrocarbons, oil, and gasoline applications Provides excellent sealability and drastically lowered emission levels.

COMPRESSED GASKET SHEET with SBR BINDER

Constructed from aramid fibers and an SBR binder this material serves in water, inert gases, and saturated steam applications (saturated steam under 150psi). Provides excellent sealability and drastically lowered emission levels.

COMPRESSED GASKET SHEET with NEOPRENE BINDER

Constructed from aramid fibers and a neoprene binder this sheet serves in water, refrigerant, oil, fuel, and saturated steam applications (saturated steam under 150psi). Provides excellent sealability and drastically lowered emission levels.

COMPRESSED GASKET SHEET with EPDM BINDER

Constructed from aramid fibers and an EPDM binder this material serves in water, inert gases, and saturated steam applications (saturated steam under 150psi). Provides excellent sealability and drastically lowered emission levels.

INORGANIC FIBER GASKET SHEET

Constructed with inorganic fibers with a nitrile binder. Reduced creep relaxation and improved torque retention provide optimal sealing. Most inorganic fiber gasket sheets are ABS Fire Safe Type approved.

OIL PAPER / VEGETABLE FIBER

Premium grade vegetable fiber sheet packing, efficiently saturated with a glue-glycerin impregnant rendered insoluble by means of a tanning agent to create a strong, flexible, all-proof packing.

HIGH-TEMPERATURE COMPRESSED SHEET

These high-temperature gasket materials excel in the harshest conditions- intense heat, high pressure, saturated steam and hot oils. The complex engineering process involves laboratory tests for fire safety. They maintain effective seal during pressure and temperature fluctuations. Superior torque retention lowers leakage rates and reduces maintenance time.

PTFE GASKET PRODUCTS

PTFE Gasket Products are flat PTFE gasketing materials. These high-performance PTFE materials are manufactured using a process that imparts unique physical properties, which are not obtainable through conventional manufacturing methods.

GRAPHITE GASKET MATERIALS

Graphite Gasket Products are flat gasketing materials composed of pure, exfoliated flake material. These materials excel in extreme conditions, withstand high temperatures, high pressures, and aggressive chemicals, and are proven fire-safe. Graphite provides a reliable seal as it seals easily under moderate bolt load, offers superior torque retention, retains dimensional stability in high temperatures and seals tightly even during pressure fluctuations. Flexible graphite is manufactured in such a manner that no organic or inorganic binders and fillers are introduced—the end product is essentially graphite with outstanding physical properties. The insertion of wire mesh, stainless steel foil, and tanged metal inserts increase strength and ease of handling.

Metal Gaskets

SPIRAL WOUND GASKETS

Metal gasket made spiral winding metal material and adding a sealing filler. Available with inner or outer rings or both.

FLANGE GASKETS

Gasket cut from various materials to seal standard ANSI flanges and other common flange dimensions.

TOPOG-E® GASKETS

The steam boiler market makes extreme demands on gaskets; Topog-E® molded rubber gaskets are specifically formulated to meet and exceed these demands and deliver industry standard performance

SELF-LOCATOR GASKETS

The SELF LOCATOR gaskets are a complete stainless steel containment of a sealing element offering a true compression seal. The patented design gives you long term reliability without flange welding and eliminates misalignment on installation. Due to its universal sizing, one gasket fits all flange pressure classes, eliminating the chance of incorrect gasket selection. The most important feature of the gasket is the high unit load generated by the narrow sealing area provides a considerably higher flange clamping pressure and a better seal at a lower clamping force. The standard gasket material is 316 SS, with two (2) tracks of Flexible Graphite sealing elements. Specialty gasket material and/or sealing elements are available as options.

SPIRAL WOUND MANWAY & HANDHOLE GASKETS

Gaskets for boiler handhole, tubecap and manhole covers incorporating the unique Flexitallic Spiral Wound profile and specially manufactured with graphite filler, are ideal for corrosive, high pressure or temperature duties. Flexitallic’s anticipation of developments in modern steam generating and engineering equipment and ability to design to specific requirements are the guarantee of the perfect seal at minimum maintenance cost with consistently high standards of performance.

We Make Spiral Wound Gaskets!

We offer custom metal windings that are made-to-order, as well as a selection of stock spiral wound gaskets readily available in our inventory!
