Met-L-Chek — 9-16V NDT Penetrant Testing Kit

Visible Dye Penetrant Inspection Kit with VP-30 or VP-31A Penetrant, D-70 Developer, and E-59A Cleaner/Remover — 9 Aerosol Cans in Cardboard Box
SKU: 9-16V

Overview

The Met-L-Chek 9-16V is a complete visible dye liquid penetrant testing kit designed for detecting surface-breaking discontinuities in suitable nonporous materials. The kit combines the primary chemical products needed for surface preparation, penetrant application, excess penetrant removal, development, and visual evaluation.

The kit contains three cans of VP-30 or VP-31A visible penetrant, three cans of D-70 nonaqueous developer, and three cans of E-59A cleaner/remover, packaged together in a convenient cardboard box.

This balanced 3-3-3 configuration provides inspection teams with multiple complete sets of penetrant-processing materials, making the kit suitable for field service, fabrication facilities, welding departments, maintenance teams, manufacturing plants, and industrial QA/QC programs.

What's Included

Note: The kit may be supplied with VP-30 or VP-31A depending on the selected or available configuration. Exact penetrant type should be confirmed when ordering.

Box Dimensions & Shipping Weight (Estimated)

Actual shipping dimensions and weight may vary depending on aerosol-can size, packaging configuration, and protective materials.

Key Specifications

Kit Component Functions

Performance Features

Complete Visible PT Chemistry Kit
Includes penetrant, developer, and cleaner/remover in one packaged system.

Three Full Product Sets
The 3-3-3 configuration provides multiple cans of each required chemical for repeated inspection work.

Visible Dye Inspection
VP-30 or VP-31A produces visible indications that can be evaluated under suitable white-light conditions.

Nonaqueous Developer
D-70 provides a contrasting developer coating and assists penetrant bleed-out from surface-breaking discontinuities.

Cleaner / Remover Included
E-59A supports both initial surface preparation and controlled removal of excess penetrant.

Portable Cardboard Packaging
The complete nine-can set is packaged together for convenient storage, transport, and field deployment.

Inspection Procedure

1. Surface Preparation

• Remove paint, scale, rust, and heavy contamination when required
• Apply E-59A to the surface or to a clean, lint-free cloth
• Wipe away oil, grease, dirt, and removable residue
• Repeat cleaning where necessary
• Allow the surface to dry completely

2. Penetrant Application

• Shake the VP-30 or VP-31A aerosol can as required
• Apply a uniform coating over the inspection area
• Ensure the surface remains adequately covered
• Allow the specified penetrant dwell time

3. Excess Penetrant Removal

For solvent-removable procedures:

• Remove initial excess penetrant with a clean, dry, lint-free cloth
• Apply a small amount of E-59A to a separate clean cloth
• Gently wipe until excessive surface background is removed
• Avoid overcleaning
• Do not flush penetrant from discontinuities
• Allow the component to dry before developer application

For water-washable procedures, where applicable to the selected penetrant:

• Use controlled water washing according to the written procedure
• Avoid excessive pressure or overwashing
• Dry the component as required before development

4. Developer Application

• Shake D-70 thoroughly before use
• Apply a thin, uniform developer coating
• Avoid heavy or uneven application
• Allow the developer to dry
• Observe the required development time

5. Inspection and Evaluation

• Inspect under the required white-light intensity
• Evaluate visible indications against the developer background
• Mark relevant indications when required
• Document results
• Apply the acceptance criteria specified by the governing procedure or code
• Perform post-inspection cleaning when required

Typical Discontinuities Detected

When used properly, the kit can help reveal discontinuities that are open to the inspection surface, including:

• Cracks
• Fatigue cracks
• Grinding cracks
• Heat-treatment cracks
• Laps
• Seams
• Surface porosity
• Cold shuts
• Surface-connected lack of fusion
• Leak paths
• Other surface-breaking discontinuities

Liquid penetrant testing does not detect discontinuities that are completely below the surface.

Compatibility

Compatible with:

• Visible dye liquid penetrant testing
• Approved Method A procedures when supported by the selected penetrant
• Method C solvent-removable procedures
• Suitable ferrous metals
• Suitable nonferrous metals
• Welded components
• Castings
• Forgings
• Machined parts
• White-light inspection equipment
• Visible-light meters
• Field and laboratory PT workflows

Compatibility should be evaluated before use on plastics, rubber, painted surfaces, adhesives, composites, and other solvent-sensitive materials.

Ideal Applications

• Weld inspection
• Structural weld evaluation
• Casting inspection
• Forging inspection
• Machined-component testing
