Best 90 Degree Elbow Compression Fittings in 2026

SUPERIOR PERFORMANCE: AquaAulos hydraulic fittings are made to the highest standards, with our JIC cap and plug kit meeting or exceeding SAE J514 conventions. These industrial heavy-duty JIC fittings are made from premium carbon steel galvanized with robust and long-lasting zinc, which prevents rust, corrosion, and degradation, even with extended use. Over time these fittings are exposed to hose fluid, so this durability is essential. You can trust our products like any leading brands, such as Parker, Eaton Aeroquip, or Gates, as they have been rigorously tested and meet the industry standards for pressure, temperature, and material strength!

PRECISION-ENGINEERED: We understand the importance of heavy-duty craftsmanship, which is exactly what we strive for in every piece in this kit. Our state-of-the-art CNC machine provides ultra-precise production, ensuring that the caps and plugs are made with fine-tolerance thread with good sealing for easy, repeated installation and removal. This extra attention to the manufacturing process enhances the adapter's performance. It provides customers with a competitive advantage through less downtime and extended equipment life, leading to increased revenues and reduced warranty costs.

AVOID COSTLY DOWNTIME: The perfect caps and plugs kit for the mechanic in you. These JIC kits seal and protect the ends of hydraulic hose and tube fittings to prevent hydraulic liquids from leaking onto the ground or into your or your client's machine. While you perform preventive maintenance, it also stops contaminants such as dirt, dust, moisture, and sand from entering and damaging your machine's sensitive and expensive parts, such as Pumps Motors, Valves, and Cylinders.

128 FITTINGS: This 128-piece JIC and ORFS hydraulic cap and plug kit by ZELCAN gives you plenty of fittings in the 6 most commonly needed ORFS and dash sizes: 4, 6, 8, 10, 12, and 16

SUPER BUILD: Our hydraulic fittings are made from 45# structural steel to withstand high heat; they are galvanized to resist corrosion in even the most punishing environments

QUALITY THREADING: These JIC and ORFS caps and plugs have precision-engineered standard threading that allows for smooth installation to hermetically seal your hoses, tubes, and pipes

Two piece construction - nut and body

Use with brass tubing

Standard fittings use short nuts

Cap for closing the end of a tube or fitting

Connects to tubing

Chemically hardened type 316 stainless steel for higher strength and greater corrosion resistance than untreated stainless steel

COMPRESSION CAP FITTING: Made of lead-free brass and can be disassembled and reassembled repeatedly. Suitable for indoor air application and are made for low to mid pressure applications. Can be used with thin-wall tubing in refrigeration equipment, air compressors, and machinery It closes and blanks off unused pipe. Put at the end of the tube.

THREADED CONNECTION has threaded tube connections that can be screwed close off end of tube. Use with copper, brass, aluminum or plastic tubing on gasoline, grease, oil, or water

MADE OF BRASS for corrosion resistance, ductility at high temperatures & low magnetic permeability. provide strong, tight, and reliable seals for any of your water treatment configurations

Fit Tube OD and Thread Size: 6mm x 1/4" G; Operating Pressure: 0-0.9MPa; Operating temperature: 0 - 60 Degree Celsius

Push to connect fitting can realize the pipeline together or disconnected without tools, mainly used for air compression systems, vacuum systems, pneumatic systems, 3D printers.

Push-to-connect tube connection on one end and male threads on the other end. A good release cap can withstand greater and stronger pressure without tripping. Even after installation, the release cap can be rotated 360 degrees.

【Thread Size】3/8" NPT Female. Note: 3/8" Thread is about 5/8" ID. Please check the product size diagram and select the size you need.

【Material】This pipe cap is made of brass for corrosion resistance, ductility at high temperatures, and low magnetic permeability. Our Pipe Cap 3/8" Female brass fittings don’t deform with Time, unlike Traditional Stainless Steel Thread Bushing or Plastic Pipe Fittings. Package include rubber gasket, it could provide strong seal without slipping.

【Excellent Threads】Female National Pipe Taper (NPT) threads for use with male threaded pipes. The pipe cap is Provided by the Well-Machined Threads and the Relative Softness of the Brass that Enables Tighter Sealing. Easy to Install or Change (Thanks to the hexagonal head that increases the bearing surface when a wrench is applied to the fitting). Doesn’t Leak!

Used with brass, copper, iron pipes (3/8" outside diameter), used to close male pipes or pipe joint ends.

Used for the connection of fuel, petroleum, air, propane, liquefied petroleum gas (LP) and natural gas pipelines.

The flare fitting at the end of the copper pipe should be firmly fixed to the fixed point by a threaded joint.
