What We Do
FABRICATION SERVICES
Comprehensive tube fabrication capabilities under one roof — from precision CNC bending and end forming to welding, brazing, and complete contract manufacturing. Eight core service areas, one trusted partner.
Tube Bending
Tube Bending

Harco provides rotary arm, ram, and roll bending processes to form almost any tubular shape. With decades of experience and a broad equipment lineup, we handle everything from tight-radius mandrel bends to large sweeping curves — in round, square, and rectangular profiles.
Processes & Capabilities
Mandrel-supported bending capable of up to 180° bends. Delivers the tightest radii and highest precision for critical applications. Ideal for complex multi-bend parts with tight tolerances.
Large-radius bends, smooth curves, and coiling for round, square, and rectangular tube profiles. Perfect for architectural, structural, and large-format fabrication work.
Produces multiple radii in a single part without a tool change. Reduces cycle time and eliminates part handling between operations for complex geometries.
Tight-radius specialty work for short runs and prototype bends. Experienced operators produce precise bends on parts that require hands-on attention to detail.
High-volume efficiency — bends both ends of a tube simultaneously. Dramatically reduces cycle time for symmetrical or dual-end parts in production quantities.
Mixed radii within a single part, producing non-constant curves and complex sweeping shapes that cannot be achieved with fixed-radius tooling.
Tube Forming
Tube Forming

Over 22 unique end-forming machines capable of producing from simplistic to extreme multi-hit forming requirements. Our equipment handles single and multi-station operations for flaring, expanding, beading, and reducing tube ends to exacting specifications.
Processes & Capabilities
Single and double-lap flares meeting MS33584, AS4330, and J533 specifications. Provides reliable, leak-free connections for hydraulic, pneumatic, and fluid transfer systems.
Increases tube diameter for joining, fitment, or assembly purposes. Both ram and segmented expansion processes are available to match the application requirements and tube material.
Creates O-ring grooves and hose connections per SAE J1231 standards. Roll and compression bead processes are selected based on tube material, wall thickness, and application demands.
Ram and segmented processes to decrease tube OD for telescoping joints, press-fit assemblies, and specialized connection requirements.
Tube Flattening
Tube Flattening

Punch press operation — a cost-effective way to produce flat tube ends. Combines flattening, trimming, and hole piercing in a single die set, reducing handling and cycle time while maintaining repeatability across high-volume production runs.
Processes & Capabilities
Symmetrical flattening centered on the tube axis. Used for mounting tabs, bracket connections, and fastener attachment points.
Offset flattening with material displaced to one side. Provides clearance advantages in tight-space assemblies and asymmetrical mounting configurations.
Combined flattening and piercing in a single stroke. Creates a finished mounting point with fastener hole, eliminating secondary drilling operations.
Integrates a bend with a flattened end, producing complex two-feature parts in minimal operations for structural and support applications.
Multi-feature die sets that flatten and form the tube end into a custom profile. Supports unique geometry requirements beyond standard flat configurations.
Specialized forming where the tube end is reshaped into a crossover profile, enabling stacking, nesting, or interlocking assembly designs.
Slotting & Notching
Slotting & Notching

Punch press or tube laser operations depending on detail and application requirements. These processes prepare tube ends for joining, assembly, and structural connections with precision cutouts that ensure proper fit-up and alignment.
Processes & Capabilities
Precision slots cut into tube walls for clip retention, spring insertion, or expansion/contraction allowance in structural assemblies.
Angled cutouts at tube ends for fish-mouth or saddle joints. Creates precise mating surfaces for welded tube-to-tube connections at specified angles.
Square or rectangular notches at tube ends for perpendicular joints, pass-through connections, and tab-and-slot assembly configurations.
Cutouts along the tube sidewall for cross-member insertion, cable routing, or branch connections without end-of-tube access requirements.
Piercing & Punching
Piercing & Punching

Tube piercing creates holes in tubular components for assembly, drainage, or fitment. Whether for fastener access, fluid passage, or decorative purposes, our piercing processes deliver clean, burr-free holes in a wide range of tube sizes and wall thicknesses.
Processes & Capabilities
Cost-effective hole-making process where pan-head bolts seat flush against the dimpled surface. Ideal for non-critical fastener holes and drainage openings where OD integrity is not required.
Maintains tube OD integrity by supporting the tube wall from the inside during piercing. Essential for telescoping joints and applications where the outer surface must remain smooth and undistorted.
For complex multi-hole patterns requiring precise positioning, our CNC-controlled and manual piercing stations handle intricate layouts, angular holes, and high-tolerance placement requirements.
Welding & Brazing
Welding & Brazing

Comprehensive welding and brazing capabilities using TIG (GTAW), MIG (GMAW), gas welding, silver brazing, induction brazing, and robotic welding. Our certified welders and advanced automation deliver consistent, high-quality joints across all production volumes.
Processes & Capabilities
Uses fuel gas and oxygen to heat assemblies above the filler metal melting point. Produces strong, leak-proof joints on copper, brass, and steel assemblies for HVAC, plumbing, and fluid systems.
Induction heating technology for precise, repeatable multi-material joints. Localized heat input minimizes distortion and enables high-speed production of brazed assemblies with consistent quality.
Arc rotated 360° around a static workpiece for uniform, full-penetration tube-to-tube and tube-to-fitting welds. Ideal for critical fluid systems requiring X-ray quality welds.
Growing automation capability with MIG and aluminum welding robots and collaborative robots (cobots). Delivers consistent weld quality at higher throughput for production volume work.
6 MIG stations, 4 TIG stations, and 5 large weld bays staffed by certified welders. Handles everything from thin-wall precision TIG work to heavy structural MIG fabrication.
Hydraulic Lines
Hydraulic Lines

Tubular hydraulic lines from ¼" to 2½" OD for heavy equipment, farm, and industrial sectors. From single prototypes to full production runs, we deliver precision-bent and end-formed hydraulic lines ready for direct installation.
Processes & Capabilities
Precision CNC bending combined with flared tube ends for reliable, leak-free hydraulic connections. Tight tolerances ensure proper routing and fitment in complex hydraulic systems.
Standard and specialty fittings including JIC (Joint Industry Council) and ORFS (O-Ring Face Seal) configurations, all manufactured to SAE specifications for system compatibility.
Send us a sample or worn-out line and we reverse engineer it to produce exact replacement parts. Ideal for legacy equipment, discontinued lines, and obsolete part numbers.
