High Precision Hydraulic Grease Nipples for Heavy-Duty Applications

Crafted from premium hardened steel with chrome plating for extreme corrosion resistance and durability. Precision-machined threads ensure leak-proof connections under high-pressure conditions. Ideal for hydraulic systems, industrial machinery, agricultural equipment, and automotive bearings.

Seamless Lubrication with Self-Cleaning Design

Features a unique ball-check valve mechanism to prevent contamination and grease backflow. The one-piece sintered brass construction eliminates weak points for consistent performance in harsh environments. Perfect for construction equipment, marine applications, and mining machinery.

Universal Compatibility with Standard Fittings

SIQ-16-ES to SIQ-100-ES series meet ISO 6149 and DIN 3404 standards for global interchangeability. CNC-turned sealing surfaces provide perfect alignment with grease guns. Essential maintenance component for fleet vehicles, manufacturing plants, and heavy transport systems.

Engineered for Maximum Load Capacity

Heat-treated steel core withstands over 10,000 PSI without deformation. Knurled base allows tool-free installation in tight spaces. Critical upgrade for logging equipment, railroad maintenance, and off-road vehicle suspensions.
