Extreme-Pressure Stainless Steel Threaded Pipe Fittings
With the strength to handle extreme pressures, these fittings can be used to connect equipment in hydraulic fluid lines. 316 stainless steel fittings have excellent corrosion resistance. BSPP and metric male threads have either a gasket or a gasket and washer to prevent leaks. UN/UNF (SAE Straight) threads are also known as O-ring boss threads; the male threads have a gasket to prevent leaks.

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. They have mounting holes, so you can mount from the top or side.
Aluminum manifolds are the industry standard for the most common types of applications. They are lighter in weight than other metal manifolds and have good corrosion resistance. Anodized aluminum manifolds have a black finish and nickel-plated aluminum manifolds have a shiny finish.
Use a plug (sold separately) to close off any unused inlets and outlets.

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, water, or hydraulic fluid to five locations from a single supply source. Manifolds have mounting holes, so you can mount from the top.
Anodized aluminum manifolds are the industry standard for the most common types of applications. They are lighter in weight than other metal manifolds and have good corrosion resistance. These manifolds are anodized for a black finish.

Instead of a metal sleeve (ferrule), these fittings have a rubber sleeve that cushions tubing and absorbs vibration to maintain a tight seal, even when connected to large pumps. However, rubber sleeves can’t withstand temperatures as high as metal ones. To create the strong seal, tighten the included nut. These fittings are made of 316 stainless steel, so they have excellent corrosion resistance. They’re also known as flareless fittings. All meet DIN 3861, which is an international standard for compression tube fitting specifications.

Push-On Barbed Hose Fittings for Hydraulic Fluid
These fittings have sharp barbs to grip rubber push-on hose with no clamps or ferrules required. The more you pull on the fittings, the tighter the hose will grip. Use them in low-pressure hydraulic applications up to 350 psi. Also known as hose nipples, they adapt a barbed end to a threaded end, so you can connect to pumps, cylinders, and other equipment in your hydraulic system. Fittings are zinc-plated steel, which has excellent strength and durability. Fittings have fair corrosion resistance.
Fittings that swivel until tightened rotate 360° for easy installation.
Note: To ensure proper connection, the barbed end has to be pushed in all the way, with the hose end concealed by the ring.

International Standard ISO Minimal-Spill
Quick-Disconnect Hose Couplings for Hydraulic Fluid
Also known as flush-face couplings, the plugs and sockets have a flat face, which allows them to mate close against each other, reducing fluid loss when connecting and disconnecting the line. A complete coupling consists of a plug and a socket (both sold separately) that connect and disconnect quickly. Use them when you need frequent access to a line. All of the International Standard ISO Minimal-Spill quick-disconnect plugs are compatible with any of the International Standard ISO Minimal-Spill quick-disconnect sockets of the same coupling size, regardless of the pipe size. Couplings are compatible with ISO 16028 Parker FEM, ISO 16028 Perfecting HT, and ISO 16028 Snap-Tite 74 couplings. Also known as double shut-off couplings, the plugs and sockets both have a shut-off valve that stops the flow when the coupling is separated. They are zinc-plated steel, which has excellent strength and durability and fair corrosion resistance.
Plugs are also known as nipples.
Note: To ensure a correct fit, make sure that the plug and socket have the same coupling size. Pressure ratings are given for static (constant) pressure conditions.
Warning: Never attempt to connect or disconnect couplings when operating at maximum pressure. Stop the flow before you disconnect the line.

Beaded Hose Fittings for Coolant
A single rounded bead grips onto hose just like a barb, but has no sharp edges that could cut or damage soft hose. This type of connection can handle higher pressures than standard barbed fittings for coolant. Slide the beaded end into rubber hose and secure with a clamp. Also known as hose nipples, they adapt a beaded end to a threaded end. Fittings are zinc-plated steel, which is strong and durable with fair corrosion resistance.

18-8 Stainless Steel Easy-to-Install Thread-Locking Inserts
Made of 18-8 stainless steel, these inserts have good corrosion resistance. Also known as E-Z Lok, they use Loctite® adhesive to keep them in place. The adhesive reaches full strength after 72 hours. They may be mildly magnetic. Installation requires a drill bit and a standard tap. Then set the insert with an installation bit, a slotted screwdriver, or a bolt with two nuts.
Choose inserts with a thick wall for greater strength than thin-wall inserts, or to fill a large hole.

18-8 Stainless Steel Key-Locking Inserts
Made of stainless steel, these inserts have good corrosion resistance. Drive the keys into the surrounding material for a more secure hold than thread-locking inserts. Use them to repair or change threads in soft metals such as aluminum. Inserts may be mildly magnetic. They’re comparable to Keensert® inserts. Installation requires a drill bit, a standard tap, an installation tool, and a hammer.
Choose inserts with a thick wall for greater strength than thin-wall inserts, or to fill a large hole.

Black-Phosphate Steel Key-Locking Inserts
A black-phosphate finish provides mild corrosion resistance. Drive the keys into the surrounding material for a more secure hold than thread-locking inserts. Use them to repair or change threads in soft metals such as aluminum. They’re comparable to Keensert® inserts. Installation requires a drill bit, a standard tap, an installation tool, and a hammer.
Choose inserts with a thick wall for greater strength than thin-wall inserts, or to fill a large hole with stripped threads.
