GRYVOZE Hydraulic Pressure Test Kit

The GRYVOZE kit includes five gauges, a comprehensive set of couplings, tees, hoses, and a portable case. Readouts cover multiple ranges to accommodate various hydraulic systems, with dual-scale gauges designed for straightforward interpretation. Best for shops or field crews needing a broad, ready-to-use testing solution for excavators and construction equipment.
Best for: users who require a wide range of gauge readings in a single kit and a durable storage solution. Better for: multi-system testing and frequent transport between job sites. Choose this if you want a complete kit that reduces the need to source separate components.
Caution: The gauge assembly uses glycerin-filled bodies to dampen pulsations; handle with care to avoid impact damage during transport.
VEVOR Hydraulic Pressure Test Kit

VEVOR’s kit presents five gauges with five measurement ranges plus 13 test couplings and 14 tee connectors. The five-range gauge setup supports precise readings across a variety of hydraulic pressures, making it suitable for excavators, construction machinery, and similar equipment. Best for: technicians who need clear, multi-range readings and a full accessory set in a sturdy carrying case.
Best for: users seeking a durable, high-clarity gauge kit that can handle different excavator systems. Better for: field service teams requiring portability and organized storage.
Limitation: While comprehensive, ensure the included fittings match your specific brand couplers to avoid adapter needs on-site.
SINOCMP 14Pcs Tee Fittings Set

This set offers 14 tee fittings in multiple sizes and thread configurations, designed for broad compatibility with excavator hydraulic systems. The maximum pressure rating is up to 9000 PSI / 600 BAR / 60 MPa. Best for: shops needing a diverse selection of tees for quick on-site assemblies. Better for: scenarios requiring many connection options in a single pack.
Best for: high-compatibility users who need many size options. Choose this if you frequently modify hoses and ports. Limitation: Some sizes may be less common in certain regional markets; verify thread types before purchase.
SINOCMP ORFS 6 Pack Hydraulic Tees

This 6-pack focuses on ORFS swivel tees for excavator hydraulic systems, emphasizing high-strength carbon steel with galvanized coating. It’s designed to withstand high pressure and temperatures, making it a solid choice for demanding applications. Best for: projects requiring ORFS-compatible swivels with robust corrosion resistance. Better for: extensions and tees that must resist pulsations and heat in tough environments.
Limitation: The set emphasizes ORFS geometry; ensure your system uses compatible sealing interfaces to avoid leaks.
SINOCMP 7Pcs JIC37 Hydraulic Tees

The 7-piece JIC37 set provides threaded run tees that are compatible with common excavator hydraulic systems. It is designed for reliable performance under high pressure, with galvanized carbon steel construction for durability. Best for: users prioritizing JIC37 connectors for standard hydraulic test setups. Better for: installations requiring tight, robust branches off a main line.
Limitation: JIC37 sizing may not fit all European or non-US standards—verify thread spec compatibility before ordering.
Bonbo Hydraulic Pressure Test Kit

Bonbo’s kit is designed for Parker PD series compatibility and other common couplers. It provides a practical option for testing and diagnosing pressure in Caterpillar, Case, and other excavator systems. Best for: users needing compatibility with PD series ports. Better for: quick, routine testing tasks in a shop or on-site work truck.
Limitation: It emphasizes PD-series compatibility; verify your exact port types to prevent adapter needs.
Buying Guide
- Max pressure compatibility: Check the highest PSI/BAR rating to match your equipment’s operating range. Higher ranges are better for heavy-duty machines but ensure your hoses and gauges can handle the same pressure.
- Connector types and compatibility: Ensure the kit includes the connection styles your system uses (JIC, ORFS, Tee configurations, etc.). A diverse set reduces the need for extra adapters.
- Gauges vs. hoses: Decide if you need standalone gauges, a gauge-filled kit, or hoses with integrated gauges. Glycerin-filled gauges reduce pulsations but require careful handling.
- Durability and materials: Look for carbon steel bodies with galvanized or stainless surfaces to resist corrosion and wear in harsh environments. Durable seals prevent leaks under pressure.
- Portability and storage: A sturdy carrying case helps transport between job sites and keeps fittings organized for quick access.
- Brand compatibility: If you work with specific brands or port types (Parker PD, Caterpillar ports), pick kits tailored to those systems to minimize adapters.
Frequently Asked Questions
- What is a hydraulic pressure test kit used for?
– It is used to test and diagnose hydraulic system pressure, verify seals, and ensure components operate within specified ranges on machinery like excavators. - Which max pressure rating do I need for excavators?
– Most heavy-duty fittings here are rated up to 600 BAR or around 9000 PSI, but verify your machine’s system pressure before purchasing. - Are ORFS and JIC37 compatible with all brands?
– Not universally. Compatibility depends on port type and seal design; confirm your system’s coupler standards. - Should I choose a multi-gauge kit or single-gauge solutions?
– Multi-gauge kits are versatile for various tests and conditions, while single gauges may be simpler and lighter for specific tasks. - Do these kits include hoses and adapters?
– Many include a broad set of couplings and tees; verify the exact contents to ensure coverage for your system’s ports. - Is a carrying case necessary?
– It helps protect fittings and keeps components organized, especially for field use.
