EPDM Rubber Metal Pipe Connector for Noise Reduction

Product Overview

• Designed specifically to reduce vibration and noise transmission in piping systems

• Combines elastic EPDM rubber with metal reinforcement for structural stability

• Effectively protects pipelines, pumps, and connected equipment from long-term fatigue

• Suitable for HVAC, water supply, industrial circulation, and mechanical rooms

• Engineered for environments where quiet operation and reliability matter most

This EPDM Rubber Metal Pipe Connector is not just a connector—it is a buffer between motion and stability, helping systems run smoother, quieter, and longer.

   

   

Structural:

Cylindrical rubber body with vulcanized flange to the flange holes (The cylindrical body: EPDM elastomer + 2pc flanged inserts). The rubber-metal pipe connector is self-sealing, so that no additional seals required. 

Product Description

In many industrial and building systems, noise does not come from failure—it comes from movement.
Pumps hum, pipes vibrate, and rigid connections quietly transmit that energy through walls, floors, and equipment frames. Over time, that vibration becomes noise complaints, loosening joints, and premature wear.

The EPDM Rubber Metal Pipe Connector for Noise Reduction was developed to interrupt that chain.

When installed, the connector introduces a soft yet controlled elasticity into the pipeline. You can almost feel it when handled—the rubber body is resilient, slightly textured, and firm without stiffness. Once operating, it absorbs micro-movements that metal pipes cannot forgive. The harsh mechanical hum softens. The system sounds calmer, more controlled, more intentional.

Unlike simple rubber sleeves, this connector integrates metal reinforcement, giving it shape memory and strength while allowing the EPDM rubber to do what it does best: flex, absorb, and recover. The result is a connector that protects both equipment and people, quietly working in the background, day after day.

Standard Specification

Component Parts

NHFLEX-C TYPE Rubber Joint Size Chart

* Stable pipeline fixed points and proper pipeline are required to absorb axial forces.
   The rubber metal pipes are installed free of tension.
   The mounting length should be 70mm, do not load on train, twist or bend position.
   The installation should be in an easily accessible location where maintenance and inspection of the system is easy to do.  
Additional seals are not required, since rubber protrudes at the sealing surface.
   Keep the joint away from heat sources such as welding machines or sun light.

   Do not assemble the joint directly in touch with rubber surface or other fitting.

Key Features

This connector focuses on outcomes engineers care about, not just specifications:

• Noticeable Noise Reduction
  EPDM rubber dampens vibration at its source, reducing structure-borne noise before it spreads.

• Vibration Isolation That Protects Equipment
  Pumps, chillers, and pipelines experience less stress, extending service life.

• Balanced Flexibility and Strength
  The metal-rubber structure prevents over-deformation while allowing controlled movement.

• Weather and Aging Resistance
  EPDM resists ozone, heat, moisture, and long-term aging—ideal for continuous operation.

• Low Maintenance, Long-Term Stability
  Once installed, the connector works silently without frequent adjustment or replacement.

FAQ

Q1: How effective is this connector in reducing noise?
A: It significantly reduces structure-borne vibration, which is one of the main causes of pipeline noise, especially near pumps and mechanical equipment.

Q2: Why is EPDM used instead of other rubber materials?
A: EPDM offers superior resistance to heat, ozone, and aging, making it ideal for long-term HVAC and water system use.

Q3: Can it handle continuous operation?
A: Yes. The material and reinforced structure are designed for continuous industrial service.

Q4: Is customization available?
A: Yes. We support customized diameters, flange standards, and pressure requirements.

Q5: Does it require frequent maintenance?
A: No. Once properly installed, it operates reliably with minimal maintenance.
