Hydraulic Hose Crimping Training

Lesson 1 • Fluid and Chemical Safety

Covers safe handling of hydraulic fluids, solvents, and lubricants used in assembly. Addresses skin contact, inhalation risks, and proper disposal of contaminated materials.

Lesson 2 • Emergency Procedures and Reporting

Outlines first-aid response, incident reporting, and equipment lockout steps. Ensures students can act decisively when accidents or near-misses occur.

Lesson 3 • Hydraulic Injection Injury Hazards

Explains the mechanism and severity of high-pressure fluid injection injuries. Motivates strict safe-work practices before any hands-on crimping activity begins.

Lesson 4 • Shop Housekeeping and Ergonomics

Defines workstation organization, slip-trip prevention, and ergonomic lifting techniques. Reduces injury risk and improves efficiency during high-volume hose production.

Lesson 1 • System Pressure and Rating Concepts

Defines working pressure, burst pressure, and safety factors for hose assemblies. Grounds students in the engineering limits that govern safe crimping outcomes.

Lesson 2 • Fitting Types and Terminology

Introduces end-fitting styles, thread forms, and sealing methods used in hydraulic assemblies. Provides vocabulary essential for all subsequent crimping and assembly work.

Lesson 3 • Hose Identification and Classification

Teaches industry-standard dash sizing, pressure ratings, and temperature ranges. Enables accurate hose selection from manufacturer catalogs and specification sheets.

Lesson 4 • Hose Construction and Materials

Examines inner tube compounds, reinforcement layers, and outer cover materials. Links material selection to pressure rating, fluid compatibility, and service life.

Lesson 1 • Machine Calibration and Setup

Covers micrometer adjustment, stroke setting, and crimp diameter verification procedures. Proper calibration ensures every crimp meets manufacturer specification.

Lesson 2 • Measuring Tools for Crimping

Introduces crimp diameter gauges, calipers, and go/no-go gauges used in quality verification. Accurate measurement is the primary quality control step after crimping.

Lesson 3 • Types of Crimping Machines

Compares bench-top, portable, and automated crimping machines by capacity and application. Guides appropriate machine selection based on hose size and production volume.

Lesson 4 • Die Sets and Collets

Explains die geometry, collet sizing, and the relationship between die selection and crimp diameter. Incorrect die choice is a leading cause of assembly failure.

Lesson 1 • Measuring and Marking Hose Length

Teaches overall assembly length calculation, cut-length allowance, and marking techniques. Accurate length ensures correct routing and fitting engagement after crimping.

Lesson 2 • Hose End Cleanliness Standards

Covers contamination sources, flushing procedures, and end-cap practices for cut hose ends. Contamination is a primary cause of hydraulic system failure in service.

Lesson 3 • Skiving and End Preparation

Explains when skiving is required, skive depth specifications, and skiving tool operation. Proper skiving ensures full fitting stem engagement and correct crimp zone.

Lesson 1 • Pre-Crimp Assembly Inspection

Establishes a systematic visual and dimensional check before the hose enters the crimper. Catching defects at this stage prevents wasted fittings and rework costs.

Lesson 2 • Fitting Insertion Depth Requirements

Defines insertion depth marks, stem engagement length, and visual verification methods. Under-insertion is a critical defect that causes fitting ejection under pressure.

Lesson 3 • Lubrication for Fitting Insertion

Specifies approved lubricants, application methods, and quantities for hose and fitting assembly. Correct lubrication prevents inner tube damage during stem insertion.

Lesson 1 • Crimping Different Hose and Fitting Combinations

Addresses die and setting changes required for spiral hose, large-bore hose, and specialty fittings. Builds adaptability across the full range of production scenarios.

Lesson 2 • Executing the Crimp Stroke

Details machine actuation sequence, stroke completion indicators, and release procedure. Consistent stroke execution is the core skill that determines crimp repeatability.

Lesson 3 • Common Crimping Defects and Causes

Identifies under-crimp, over-crimp, oval crimp, and ferrule cracking defects with root causes. Defect recognition enables immediate corrective action before assemblies enter service.

Lesson 4 • Crimp Diameter Measurement

Teaches measurement location, axis orientation, and acceptance criteria for finished crimps. Diameter measurement is the primary quantitative quality gate for every assembly.

Lesson 1 • Dimensional Verification Methods

Covers overall length measurement, crimp diameter confirmation, and insertion depth verification. Dimensional checks confirm the assembly matches the engineering specification.

Lesson 2 • Assembly Marking and Traceability

Establishes labeling requirements, batch coding, and traceability records for finished assemblies. Traceability enables rapid field recall and root-cause analysis of failures.

Lesson 3 • Non-Conformance and Rework Procedures

Defines disposition options for rejected assemblies, rework limits, and scrap authorization. Proper non-conformance handling prevents defective assemblies from reaching customers.

Lesson 4 • Proof Pressure Testing

Explains proof test pressure levels, test duration, and pass/fail criteria for hose assemblies. Pressure testing validates structural integrity before assemblies enter service.

Lesson 1 • Process Optimization and Repeatability

Introduces statistical process control concepts, crimp diameter trending, and machine capability assessment. Optimization reduces scrap rates and improves first-pass quality.

Lesson 2 • Field Repair and Emergency Crimping

Covers portable crimper deployment, field measurement without full tooling, and temporary repair limits. Enables safe, effective hose replacement in remote or time-critical situations.

Lesson 3 • Root-Cause Analysis of Hose Failures

Applies structured failure analysis to burst, leak, and fitting-ejection events using physical evidence. Systematic analysis prevents repeat failures and supports warranty claims.

Lesson 4 • Customer and Application Requirements

Interprets customer engineering drawings, application data sheets, and special approval requirements. Aligns production output with end-use performance and contractual obligations.
