VINYL-FLEX® cap punching and cutting

Electrical, automation and automotive applications often need a protective cap to do two jobs: protect a joint or thread while allowing a wire or cable to pass through. VINYL-FLEX® meets this need with precision punching of a round hole in the wall or closed end of a flexible PVC cap. The material’s natural elasticity (60 Shore hardness) grips the cable without extra seals. Combined with cutting to length, it creates a compact gland with precise dimensions, ready to fit.

Clean round holes without fraying or deforming the material
Holes can be placed in the closed end or side wall
Flexible PVC (60 Shore) forms a natural seal around the cable
Material resists acids, bases and salts
Can be combined with cutting and pad printing in one order
Consistent hole diameters and positions across production batches

Cap punching — round cable openings

We punch or cut a clean round opening directly in the wall or closed end of the cap. A precision tool leaves a neat edge without fraying. Flexible VINYL-FLEX® PVC VINYL-FLEX® (60 Shore hardness) retains its elasticity and structure during punching. The material around the hole does not tear or deform. Its elasticity lets the opening grip the cable and form a natural seal without extra sealing parts.

We position holes precisely to your drawing or sample. Specify the hole diameter, position (closed end or side wall) and distance from the edge. In serial production, we keep hole positions and diameters consistent throughout the batch.

Combining punching and cutting

Punching is especially effective with cutting. We first shorten the cap to the required length, then punch a hole in its closed end to match the cable diameter. The resulting compact flexible PVC gland protects the joint, guides the cable and helps keep out dust and moisture.

This combination is popular in electrical engineering, automotive production and industrial automation. Compared with rigid PVC or polyamide glands, punched VINYL-FLEX® caps seal better thanks to their natural flexibility, fit without tools and resist vibration.

Applications for glands and cable seals

Punched flexible PVC caps serve many industrial applications. They act as cable glands in metal switchboards and cabinets, protecting wire insulation from sharp sheet edges. They can also protect sensor or thermostat outlets on tubes. In vehicles, they protect cable harnesses passing through body panels or engine partitions. Flexible PVC resists acids, bases and salts, so these glands work in demanding chemical environments.

Typical uses

Cable outlets and glands for terminals and switchboards Covers for automotive connectors and sensors with cable outlets Protective ends for electrical conduit and flexible tubing Insulating boots for spade connectors with cable outlets Glands for temperature and pressure sensors in industrial equipment

Frequently asked questions

Yes. Flexible VINYL-FLEX® PVC (60 Shore hardness) resists tearing. The punched hole retains its shape as a cable is pulled through and then flexes to fit the cable diameter.
Yes. Depending on the cap type and production requirements, holes can be placed in either the closed end or the side wall. Specify the location in your drawing or technical enquiry.
This may be possible depending on the part size and hole diameters. Send us a drawing so we can assess feasibility and recommend a solution.
The range depends on the cap size and the tool used. Contact us with the cap type for the minimum and maximum possible hole diameter.
The flexible PVC edge adapts to the cable diameter and forms a natural seal. VINYL-FLEX® material has strong sealing properties that have also been tested with pressurised helium.
Yes. Flexible VINYL-FLEX® PVC resists acids, bases and salts. It also resists abrasion, UV and weathering, making punched caps suitable for demanding industrial settings.
