302026-1-Coning-Kit
Product Name: Coning Kit / High-Pressure Tube End Preparation Kit (Part No. 302026-1)
Description:
The Coning Kit 302026-1 is a specialized manual tool set used to machine the sealing surface on the ends of high-pressure (HP) stainless steel tubing. It is specifically engineered to create the precise 60-degree cone seat required for metal-to-metal high-pressure seals. By generating the correct angle and surface finish, the kit ensures a leak-tight connection when the tube is assembled with a compatible gland nut and coupling.
Applications:
Preparing the ends of HP tubing for installation in waterjet cutting systems, intensifier pumps, and high-pressure manifolds.
Replacing a damaged tube section by cutting the tube to length and coning the new end on-site.
Servicing the plumbing of check valves, on/off valves, and cutting head swivels.
Capable of handling common HP tubing sizes such as 1/4 inch, 3/8 inch, and 9/16 inch.
Features:
Precision Cone Angle: Designed to machine the industry-standard 60-degree conical sealing surface for reliable HP connections.
Manual Operation: Operates via a hand-held drive mechanism or drill attachment, eliminating the need for a lathe.
Durable Construction: Hardened cutting blades or bits designed to withstand the stresses of work-hardened stainless steel.
Integrated Stop Depth: Includes a depth stop or pilot guide to ensure the cone is cut to the correct depth without over-cutting the tube wall.
Maintenance:
Cutting Oil: Always use a high-quality sulfur-based cutting oil on the tool and tube during the cutting process to prevent galling and extend tool life.
Blade Sharpness: Regularly inspect the cutting blades or bits for dullness or chipping. Replace worn cutting elements immediately to prevent poor surface finish.
Cleaning: Clean the tool thoroughly of metal shavings and residual oil after each use to prevent corrosion.
Storage: Keep the kit components in a protective case to maintain the sharpness of the cutting edges and prevent damage to the guides.
