Product Description
Product Overview
Thread double ball rubber soft joints, commonly known as flexible rubber joints, are engineered for ground source heat pump systems. Constructed from premium materials including EPDM, neoprene, and natural rubber, these joints automatically accommodate natural weather-induced expansion and contraction. The threaded connection system enables flexible installation with excellent shock absorption capabilities.
Material Specifications
Threaded rubber joints are available in multiple material combinations to suit various application requirements:
- Metal Components: Carbon steel, 304 stainless steel, 316 stainless steel
- Rubber Materials: Natural rubber, EPDM rubber, nitrile rubber, butyl rubber
- Material Selection: Based on fluid properties including acid resistance, alkali resistance, oil resistance, and heat tolerance
Structural Design
Each threaded rubber joint features a multi-layer construction:
- Inner rubber layer for fluid compatibility
- Multi-layer nylon cord reinforcement for structural integrity
- Outer rubber layer for environmental protection
- Metal union joint for secure threaded connections

| 65-80 | 265-285 | 8-10 | 24 |
Installation Procedure
Step-by-Step Installation
- Preparation: Clean pipes and joints thoroughly; inspect rubber seals for integrity
- Positioning: Determine installation location based on connected pipe/equipment position
- Seal Placement: Position rubber seal at pipe port, ensuring complete coverage without twisting
- Connection: Align joint threads with pipe threads and tighten securely using appropriate tools
- Testing: Conduct hydrostatic test to verify complete sealing and eliminate leakage
Critical Installation Notes
- Perform visual inspection for defects before installation
- Apply 3-4 wraps of threaded sealing tape for enhanced sealing
- Tighten evenly without excessive force to prevent thread damage
- Avoid over-tightening to prevent joint deformation
- Adjust joint angle as needed for optimal pipeline connection stability
