FAQ
What thread types are used in Komatsu hydraulic fittings?
Most Komatsu machines use Metric threads, but some models also incorporate BSP, JIC, or ORFS depending on the circuit type.
Are your Komatsu fittings designed for high-pressure systems?
Yes. Our fittings are engineered to handle up to 6000 PSI, making them suitable for critical high-pressure applications in Komatsu excavators, loaders, and dozers.
Do you offer both straight and angled fittings for Komatsu equipment?
Yes. We supply straight, 45°, and 90° elbow fittings, along with tees and banjo types, to accommodate different hose routing needs.
What materials are Komatsu hydraulic fittings made from?
Standard fittings are made from carbon steel for strength and durability. Stainless steel and brass options are available for specific environments.
What surface treatments are available for corrosion protection?
Fittings are available with zinc-nickel plating, electro-galvanized coating, or phosphate black finish, depending on environmental and operating conditions.
What are the size ranges for Komatsu fittings?
Our Komatsu-compatible fittings cover:
Metric: M10×1.0 to M42×2.0
JIC: 1/4” to 2”
Other sizes can be customized on request.
Can Komatsu fittings be used for hydraulic cylinders and pumps?
Yes. Our fittings are suitable for all hydraulic components on Komatsu machines, including cylinders, valves, pumps, filters, and hoses.
What sealing methods are used in these fittings?
Depending on the type, sealing methods include: Metal-to-metal cone seal (JIC 37°)/O-ring face seal (ORFS)/Thread + sealant (NPT)/Washer + bolt seal (banjo)
Are your Komatsu fittings reusable or single-use?
Most metal hydraulic fittings are reusable if properly removed without damage. However, for critical high-pressure use, we recommend replacement to ensure safety.
Do you offer pressure testing or burst pressure data for these fittings?
Yes. All fittings undergo leak and burst tests during production. Detailed pressure specifications and safety factors are available upon request.
