Value Brand

Value Brand Blind Flange 1" Welded Black

SKU CH-WKCX-BZQFT

Blind flange terminates 1 in pipe with a welded steel connection rated to 150 psi

  • Blind flange seals pipe ends securely
  • Welded steel construction handles 150 psi pressure
  • Class 150 rating suits Schedule 40 piping systems
  • Four bolt holes simplify alignment and installation
  • Anodised finish resists corrosion from -29 °F to 425 °F

1" Welded Blind Flange

This Zoro Select blind flange closes a 1-inch nominal pipe with a welded, raised-face design. The steel body carries an anodized black finish and meets A105 Class 150 specifications for standard piping systems. It is intended for installers who need a permanent end-cap on Schedule 40 pipe runs.

Four-bolt mounting with 3 1/8" circle

Four 5/8-inch bolt holes on a 3 1/8-inch bolt circle align with matching Class 150 flanges for a secure joint. The 4 1/4-inch outside diameter and 1/2-inch flange thickness provide a rigid sealing surface that resists distortion during tightening. The 1 15/16-inch overall length keeps the assembly compact in tight pipe galleries.

Replaces threaded caps or temporary plugs

This flange upgrades from removable caps when a leak-tight, permanent closure is required for 150 psi service between -29 and 425 degrees F. The jump is worth it when maintenance intervals must be eliminated and the piping material is compatible with A105 steel. California Proposition 65 warnings apply for cancer and reproductive-harm chemicals.
