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.
WIDE RANGE OF APPLICATIONS: Our hydraulic cap and plug kit are designed for intense industrial settings, being able to withstand high PSI pressure levels and temperatures, even in extreme operating environments. This hydraulic cap and plug kit are great to use in test-point and diagnostic settings and in fluid power and fuel delivery applications, especially those using high pressure. This makes the fittings suitable as aerospace adapters, in chemical processing plants, agriculture, trucks, and more.
COMPREHENSIVE & COST-EFFECTIVE KITS: We have assembled this kit, based on our years of experience, to include the six most used caps and plugs sizes: #4 (7/16-20), #6 (9/16-18), #8 (3/4-16), #10 (7/8-14), #12 (1 1/16-12), #16 (1 5/16-12). All 64 pieces will be packed in sturdy, transparent, impact-resistant cases; they can be used as a storage box, keeping the set secure and organized. To compete with leading brands, we ensure that our hydraulic cap and plug kit is economically priced while still being fully effective. You don't have to break the bank when you purchase your fittings kit in whichever industry you work in.
