Custom Pebax Outer Sheath Tube with Printed Scale Markings

This Pebax outer sheath tube is a custom-manufactured medical tubing component featuring precision-printed black scale markings along the shaft. Produced in a blue, flexible Pebax (PEBA) construction, it is designed as the outer sheath layer of interventional devices, providing a smooth, stable channel for the delivery of guidewires, catheters, and other instruments during minimally invasive procedures.

Every unit is made to order by Bova (Kunshan Bova Plastic Co., Ltd.) under OEM/ODM programs, meaning dimensions, material grade, printed content, and post-processing are all tailored to the customer's device design and drawing.

Key Features and Benefits

Precision-Printed Scale Markings

The shaft is printed with clear black scale markings that serve as a visual depth reference during clinical use. Marking position, interval, and content (scale lines, text, logos, or batch codes) can be customized to your drawing — from simple tick marks to full multi-zone printing.

Balanced Flexibility and Pushability

Pebax offers an ideal balance of softness, kink resistance, and column strength. The tube tracks well through anatomy while maintaining pushability for controlled device advancement — a combination that makes Pebax a preferred outer sheath material in interventional device design.

Fully Custom Dimensions and Geometry

Inner diameter, outer diameter, wall thickness, working length, hardness, and lumen configuration (single or multi-lumen) are manufactured to your specification, with tight dimensional control maintained throughout the extrusion run.

Consistent Surface and Reliable Ink Adhesion

A smooth, uniform surface supports reliable printing quality and smooth device movement. Medical-grade inks and process controls are applied per project to keep printed marks legible and durable.

Cleanroom Post-Processing and Full Traceability

Secondary processing, inspection, and packaging are controlled and documented with batch traceability, supporting your own device quality system requirements.

Pebax Sheath Tube

Material — Medical-Grade Pebax (PEBA)

Pebax (polyether block amide) is a medical-grade thermoplastic elastomer widely used in catheter and sheath applications. It provides:

• Wide hardness range — typically Shore 25D to 72D (grades such as 3533, 4033, 5533, 6033, 6333, 7233), allowing the sheath stiffness to be tuned to the procedure;

• Excellent flexibility and kink resistance — important for navigating tortuous anatomy;

• Good dimensional stability — supports thin-wall designs with precise tolerances;

• Suitable for further processing — tipping, flaring, printing, and lamination with braided or coiled reinforcement.

If your design requires a different durometer or a composite structure (e.g., braid-reinforced outer sheath), our engineering team can advise on grade selection.

Printing and Marking Capabilities

As a dedicated secondary-operation service, Bova supports a full range of marking options on Pebax sheaths:

• Scale markings — tick or line intervals (e.g., 1 mm / 5 mm / 10 mm) positioned per drawing;

• Text and symbols — product names, logos, size labels, or orientation marks;

• Process options — [laser printing / inkjet / pad printing as per design and material];

• Print verification — legibility, position, and durability checks included in the QC flow.

Customization Options (OEM/ODM)

Quality and Manufacturing

• Precision extrusion — dedicated medical-grade extrusion lines with controlled process parameters;

• Dimensional inspection — in-house measurement (projection inspection, tensile testing) per batch;

• Secondary processing — printing, tipping, flaring, and other post-processing in a controlled environment;

• Traceability — batch records and QC documentation available for your device file;

• Certifications — relevant quality-system certifications and test reports are available for review on request.

Frequently Asked Questions (FAQ)

Q1: What is a Pebax outer sheath tube used for?

A: It is used as the outer sheath layer of interventional medical devices. It provides a smooth channel that helps guidewires and catheters travel to the target site, while its printed scale markings serve as a depth reference during placement.

Q2: Can the printed scale markings be customized?

A: Yes. The interval, position, and content of the printed marks (scale lines, text, logos, or batch codes) are produced according to your drawing, and print quality is verified during inspection.

Q3: Which Pebax grades do you offer?

A: We extrude a range of medical Pebax grades such as [3533, 4033, 5533, 6033, 6333, 7233], covering soft to firm durometers. Our engineers can help select the right grade for your application.

Q4: Do you support OEM/ODM customization?

A: Yes. Dimensions, material, printing, packaging, and post-processing are all customized to your design. Both OEM and ODM programs are supported.

Q5: What are the MOQ and lead time?

A: MOQ and lead time depend on size, printing content, and quantity. Please send your specification for a project-specific quote; prototyping with smaller quantities is available.

Q6: Do you supply sterile or non-sterile products?

A: Components are typically supplied non-sterile (sterile-ready) and packaged per your requirement. Sterilization compatibility can be discussed based on your final device process.

Q7: What quality inspection is performed?

A: Dimensional inspection, print legibility and position checks, visual inspection, and batch traceability are included. Additional test reports can be arranged per agreement.
