Flanged Rubber Expansion Joint (Single Sphere) – Vibration Isolator | DELCO

✅Superior Vibration & Noise Absorption
The high-elasticity rubber sphere acts as a dampener, effectively isolating mechanical vibration and noise generated by pumps, compressors, and fans. This prevents stress transmission to the piping system and extends equipment service life.
✅Compensates for Misalignment & Displacement
Engineered to handle multi-directional movement, including axial compression, axial extension, lateral deflection, and angular displacement. This flexibility corrects minor installation misalignments and accommodates thermal expansion/contraction.
✅High-Pressure Reinforced Body
The rubber body is constructed with multiple layers of high-strength nylon tire cord fabric (not just cotton), ensuring a high bursting pressure (Safety Factor 3:1) and stability under working pressures of PN10, PN16, or PN25.
✅Versatile Rubber Materials (EPDM/NBR)
We offer specific rubber compounds for different media: EPDM for hot water, steam, and weathering resistance; NBR for oil and hydraulic fluids; and CR (Neoprene) for seawater applications. Inner PTFE lining is available for aggressive chemicals.
✅Rotating Flanges for Easy Installation
Equipped with floating (rotating) flanges in Carbon Steel (Galvanized/Painted) or Stainless Steel. The rotating design allows for easy bolt hole alignment during installation, significantly reducing labor time on site.
