Product Description

I. Overview

Vacuum rubber tubing is specifically designed for vacuum systems with uniform wall thickness, excellent negative pressure resistance, and minimal deformation under vacuum conditions. Ideal for rotary evaporators, vacuum pumps, vacuum ovens, and more.

Available in ID 4~25mm with wall thickness 3~6mm. VMQ offers a wider temperature range (-60~250°C), while NBR offers better oil resistance.

🔬 Product Advantages:
Vacuum Rated — -0.095MPa, minimal deformation under vacuum
Uniform Wall Thickness — Ensures vacuum sealing integrity
Multi-Material — VMQ/NBR for different environments
Dimensionally Stable — Maintains structure under vacuum
Vacuum-Grade — Specifically designed for vacuum systems

II. Key Performance Parameters

Material: VMQ / NBR
ID Range: 4~25mm
Wall Thickness: 3~6mm
Vacuum Rating: -0.095MPa
Temperature Range: -60~250°C (VMQ) / -30~120°C (NBR)
Applications: Rotary evaporators, vacuum pumps, vacuum ovens

III. Material & Manufacturing

Manufactured from high-quality VMQ or NBR via extrusion molding. Features uniform wall thickness, smooth surface, and no bubbles for long-term stability under vacuum conditions.

VMQ offers a wider temperature range (-60~250°C), while NBR offers superior oil resistance for oily media environments.

Selection Guide

I. Select by Material

Material	Properties	Applications
VMQ	-60~250°C, wide temperature range	High/low temp vacuum, food-grade
NBR	Oil-resistant	Oily media vacuum systems

II. Select by ID

4~8mm: Micro vacuum systems, fine tubing
10~15mm: Standard vacuum, rotary evaporators (most common)
20~25mm: High-flow vacuum, vacuum ovens

💡 Selection Tips: Rotary evaporators choose ID 10~15mm.
Vacuum pump connections choose ID 12~20mm.
High/low temp choose VMQ.
Oily media choose NBR.

Operation & Maintenance

User Guide

I. Preparation

Inspect tubing for any visible damage
Confirm size matches vacuum system ports
Check for uniform wall thickness

II. Installation

Cut to required length
Moisten the tube end for easier fitting
Use hose clamps or ties to secure connections
Check all connections for leaks before operation

💡 Tips from Experienced Technicians: "Use clamps" — Secure vacuum tubing with hose clamps or ties to prevent disconnection.
"Avoid sharp bends" — Avoid sharp bends to prevent tube collapse.
"Regular inspection" — Check for cracks or aging and replace promptly.
"Chemical compatibility" — Vacuum tubing is not solvent-resistant — check compatibility.
