Industrial coolant pipes are made from acetal/POM (polyoxymethylene), the same engineering thermoplastic used in Loc-Line systems. Excellent chemical resistance to cutting fluids. Temperature range: -40°F to 230°F. We also offer glass-filled nylon (higher rigidity), polypropylene (food-grade), and ESD-safe conductive plastics (electronics).
Yes, our standard flexible coolant pipes are 100% physically compatible with standard Loc-Line modular hose dimensions and vacuum systems, allowing for seamless integration into your existing setups.
Three standard diameters: 1/4 inch (6.35mm), 3/8 inch (9.5mm), and 1/2 inch (12.7mm). All use the same universal ball joint. Segment lengths: 23.5mm, 25mm, and 27mm. Custom diameters from 3mm to 20mm available for OEM orders.
For standard product stock, there is no strict MOQ. For custom brand colors, private-label packaging, or custom geometries, please contact our support team for specialized wholesale quotes.
Our standard acetal series handles regular industrial coolant flow up to 30–50 PSI. For high-pressure requirements, our glass-filled nylon series offers enhanced mechanical strength and higher pressure limits.
Each standard segment adds ~0.9 inch (23mm) of reach. Measure distance from inlet to nozzle, divide by 0.9. Example: 12 inch reach = ~14 segments. More segments = finer positioning. We can pre-assemble to your spec.
