Met-L-Chek — Penetrant Inspection Kit
Visible Dye Liquid Penetrant Testing Kit with VP-30 Penetrant, E-59A Cleaner/Remover, and D-70 DeveloperSKU: 29800
Overview
The Met-L-Chek Penetrant Inspection Kit is a complete visible dye liquid penetrant testing package designed for detecting surface-breaking discontinuities in suitable nonporous materials. It combines the essential materials required for surface preparation, penetrant application, excess penetrant removal, and indication development.
The kit includes one can of VP-30 visible red penetrant, two cans of E-59A cleaner/remover, and one can of D-70 nonaqueous developer. This configuration provides additional cleaner/remover for both initial surface preparation and controlled excess-penetrant removal during inspection.
VP-30 enters surface-breaking cracks, laps, seams, porosity, and other discontinuities through capillary action. After the excess penetrant is removed with E-59A and D-70 developer is applied, penetrant retained inside discontinuities bleeds back to the surface, producing visible red indications against the developer’s contrasting background.
SKU 29800 is suitable for field inspections, welding operations, fabrication facilities, maintenance departments, manufacturing plants, and industrial QA/QC programs.

Performance Features
Complete Three-Part PT System
Includes the penetrant, cleaner/remover, and developer required for a standard visible dye penetrant inspection workflow.
Visible Red Indications
VP-30 produces red indications that can be evaluated under suitable white-light conditions without requiring a UV-A lamp.
Dual-Purpose Cleaner/Remover
E-59A can support initial surface cleaning and controlled Method C excess-penetrant removal.
Nonaqueous Developer
D-70 provides a contrasting developer coating that helps draw penetrant from surface-breaking discontinuities.
Two Cleaner/Remover Cans
The additional E-59A can supports surface preparation, penetrant removal, and repeated inspection work.
Portable Aerosol Configuration
All included materials are supplied in convenient aerosol form for field and localized inspection applications.
User-Friendly Design

Inspection Procedure
1. Surface Preparation
Remove paint, scale, rust, coatings, and heavy contamination when required
Apply E-59A to the surface or to a clean, lint-free cloth
Wipe the inspection area until oil, grease, dirt, and removable residues are eliminated
Repeat cleaning when necessary
Allow the surface to dry completely before applying penetrant
2. Penetrant Application
Shake the VP-30 aerosol can as required
Apply a uniform coating over the complete inspection area
Ensure the surface remains adequately covered during the required dwell period
Allow the penetrant to remain on the surface for the time specified by the written procedure
3. Excess Penetrant Removal
For Method C solvent removal:
Remove the initial excess penetrant with a clean, dry, lint-free cloth
Apply a small amount of E-59A to a separate clean cloth
Wipe the surface gently until excessive red background is removed
Replace contaminated cloths as required
Avoid spraying remover directly onto the inspection surface unless permitted
Do not overclean or flush penetrant from discontinuities
For Method A water washing:
Use controlled water pressure and temperature as specified by the procedure
Avoid overwashing the component
Dry the surface as required before developer application
4. Developer Application
Shake the D-70 can thoroughly before and during use
Apply a thin, uniform developer coating
Avoid applying an excessively thick layer
Allow the developer to dry and remain on the surface for the specified development time
5. Inspection and Evaluation
Inspect the component under the required white-light intensity
Evaluate red indications against the developer background
Mark and document relevant indications
Apply the acceptance criteria specified by the governing procedure or standard
Perform post-inspection cleaning when required
