New High Performance BDI Barbed Couplers
« Return to News
Blue Diamond announces a line of couplers specifically designed to meet ASTM F2176 (www.astm.org). F2176 is the specification written specially for HDPE (high density polyethylene) conduit couplers used in the power and communications industry. Performance features include high mechanical pull out and long term constant load resistance. Sustained pressure testing requirements provide assurance of integrity under high cable blowing pressures and long term water tightness.
ASTM F2176 requirements are as follows:
Short Term Mechanical Pull Out 1000 hr. Constant Load Resistance
3/4" IPS 380lbs 190 lbs
1" IPS 760lbs 380 lbs
1-1/4" IPS 940lbs 470 lbs
1-1/2" IPS 1220lbs 610 lbs
2" IPS 1920lbs 960 lbs
Sustained Internal Pressure Test (1 hour): 150 psi
Sustained External Pressure Test (1000 hrs): 10psi
The sharp barbs machined into the interior of the aluminum coupling bite into the body of the duct to accomplish outstanding pull out strength. Each barb acts as a pressure seal to allow long cable blowing lengths under high internal back pressures. The external pressure test ensures long term joint performance protecting cables from outside elements. The aluminum construction is corrosion resistant in most common soils for extremely long term performance characteristics.
The Blue Diamond Barbed Coupler is a compression fitting and must be installed using a Hydraulic or Mechanical coupling press. The coupling press ensures the HDPE conduit ends butt up against each other to enhance cable blowing. It also compresses the coupling forcing the barbs into the duct, ensuring great pull out strength and sealing capacity. Long haul telecom contractors prefer barbed compression couplings because of their reliability and ease of installation. The Blue Diamond Barbed Coupler provides all of these benefits at an affordable price.
