Quick Detail:
Different Names: Steel Injection Packers/PU Grouting Packers
Quick Description: RUTH Steel Injection Packers are designed for extreme pressure grouting in dams and tunnels. High-strength steel ensures no breakage or shearing. Factory direct bulk supply.
Description:
RUTH Steel Injection Packers are the ultimate choice for professional contractors facing tough concrete and extreme injection pressures. Unlike aluminum packers that may shear off or deform under high torque, our high-pressure injection packers are machined from premium hardened steel to ensure maximum durability.
Designed for critical infrastructure projects like dam crack repair injection and tunnel waterproofing, these mechanical injection packers provide a secure, leak-free connection even when injecting high-viscosity resins at pressures exceeding 5000 psi.
Premium Corrosion Resistance:
Construction sites are harsh, wet environments. To ensure longevity during storage and reliability on-site, every RUTH Steel Packer undergoes a rigorous Zinc Plating (Galvanization) process. This protective coating prevents premature oxidation and rust, ensuring the threads remain clean and the Zerk fittings function smoothly, even after long-term ocean shipping or storage in humid warehouses.
Applications:
Subway, tunnel, culvert, activated sludge tank, Concrete crack seepage, leakage stop underwater
Basement, underground garage, underground passage, crevice in concrete slab Through-wall pipe, corner, leakage of water

Key Features & Advantages
Unbreakable Design: Made from high-grade steel, these packers will not snap or shear off inside the hole, preventing costly redrilling (injection packers suppliers).
Extreme Pressure Rating: Engineered to withstand the massive back-pressure generated by expanding hydrophobic polyurethane grout.
Deep Penetration: Available in longer lengths (up to 30cm+) for intersecting deep structural cracks.
Secure Grip: Equipped with high-toughness rubber sleeves that expand aggressively to grip the hardest concrete.

CONSTRUCTION METHOD
01 Find Cracks
For wet base layers, first clean accumulated water; for dry base layers, clean surface dust. Carefully find cracks and mark them with a crayon or chalk.
02 Drilling
According to the concrete structure thickness, drill holes 50-150mm away from the crack on both sides along the crack direction, intersecting the crack. The drill bit diameter is 14mm. The intersection with the crack cross-section should be at an angle of 45-70 degrees, and intersect within 1/2 of the structure's thickness.
03 Bury Water-Stop Needle
Use a tool to bury and fasten the needle, ensuring the rubber part of the water-stop needle and the hole wall are dry before use, otherwise, it is easy to cause slippage when tightened.
Tips for Construction
First, analyze the cracks and take samples separately according to different crack widths and lengths to determine the pattern of crack depth development.
If the surface is not easy to dry, a spray gun can be used to dry it. If there is water in the crack, it can be detected immediately, improving work efficiency.
Safety Cautions
Pay attention to construction safety.
Wear appropriate protective gear during construction
Why Choose Steel Over Aluminum?
Hard Concrete: If you are drilling into high-grade concrete (e.g., dams, nuclear plants), aluminum is too soft. You need steel injection packers.
Safety: At high pressures, a broken packer can become a dangerous projectile. Steel ensures operator safety.
Reliability: Zero deformation means the high pressure grease coupler always fits perfectly, preventing leakage.
Primary Applications
Dam & Hydroelectric Repair: Sealing high-pressure water leaks where standard packers fail.
Tunnel & Subway: Tunnel waterproofing grout repair requires robust equipment that can handle harsh environments.
Deep Structural Repair: Injecting structural epoxy resin into deep voids in bridges and pillars.
Specialized Configurations & Accessories:
1. Button Head Packers: We offer Button Head type packers for secure, high-volume injection applications.
2. Serviceable Flat Couplers: Unlike standard disposable couplers, our matching Slide Couplers (Flat Head) are designed for longevity. The internal rubber washer and spring are fully replaceable. When wear occurs, simply replace the internal kit instead of the whole coupler—ensuring consistent high-pressure sealing and significantly extending the tool's service life.
