Product Description

I. Overview

Rubber elbow connectors are specialized fittings for directional changes in tubing systems. Manufactured from high-quality silicone rubber (VMQ) or nitrile rubber (NBR), available in 90° and 45° angles, compatible with 6~20mm ID rubber or silicone tubing.

Easy to install with reliable sealing, suitable for condenser water elbow connections, tubing directional changes, and equipment interface connections.

🔬 Product Advantages:
Two Angles — 90°/45° for different directional needs
Multiple Sizes — For ID 6~20mm full coverage
Two Materials — VMQ/NBR for different environments
Easy Installation — No special tools required
Reliable Sealing — Leak-proof connections

II. Key Performance Parameters

Material: VMQ / NBR
Angle: 90° / 45°
For ID: 6~20mm
Temperature Range: -60~250°C (VMQ) / -30~120°C (NBR)
Applications: Directional changes, condenser elbows, equipment interfaces

III. Material & Manufacturing

Manufactured from high-quality VMQ or NBR via precision compression molding. Features smooth inner and outer walls, accurate dimensions, and precise angles for perfect tubing fit.

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

Applications

Typical Applications

Condenser Water Elbows

90° turns at condenser water inlets/outlets

Tubing Directional Changes

Direction changes in tubing systems

Equipment Interface Connections

Between equipment and tubing lines

Lab Piping Systems

Various liquid and gas line turns

Applicable Fields

Chemistry Labs

Pharmaceutical Industry
Teaching Labs

Selection Guide

I. Select by Angle

Angle	Applications
90°	Right-angle turns — most common (condenser elbows, vertical turns)
45°	Gentle turns — for space-constrained or smooth transitions

II. Select by Material

VMQ: Wide temperature range (-60~250°C), for high/low temp and food-grade
NBR: Oil-resistant, for oily media environments

💡 Selection Tips: Condenser water choose 90° VMQ elbow.
Oily media choose NBR.
Space-constrained choose 45° elbow.
High temperature choose VMQ.

Operation & Maintenance

User Guide

I. Preparation

Confirm angle and size match installation requirements
Inspect the connector for any visible damage
Verify material compatibility with temperature and environment

II. Installation

Insert each end of the connector into the corresponding tubing
Adjust the angle to the desired direction
Secure with hose clamps or ties
Check all connections for leaks before operation

💡 Tips from Experienced Technicians: "Insert both ends first" — Connect both ends to tubing before adjusting angle.
"Don't over-twist" — The angle is fixed; don't force beyond the design angle.
"Material matching" — High temperature choose VMQ, oily media choose NBR.
"Regular inspection" — Check for aging or deformation and replace promptly.
