Description
3" Two-Piece Cast Iron Lever Clamp
3" Two-Piece Cast Iron Lever Clamp provides a two-piece grooved connection for compatible 3" piping and equipment assemblies.
Constructed with a ductile iron housing, the Dixon L03BU is designed for compatible 3" grooved connections with a 3.500" pipe OD. The assembly includes a nitrile rubber gasket and two-bolt housing for secure installation.
Product Highlights
Two-piece iron coupling designed to join compatible 3" grooved pipe and equipment connections.
The L03BU uses a nitrile gasket with a two-bolt housing for secure grooved-system installation.
Technical Specifications
Grooved Connection Configuration
The first side engages a compatible 3" grooved pipe or equipment connection with the proper 3.500" outside diameter.
The opposite side engages the second compatible grooved component while the internal nitrile gasket seals across the joint.
Two-Piece Cast Iron Lever Clamp Design
The Dixon L03BU is designed for compatible 3" grooved piping with a specified 3.500" pipe outside diameter. The two-piece housing fits around the prepared grooves and provides the mechanical connection between the mating components.
Confirm the pipe OD and groove configuration on both mating components before installation because proper housing engagement depends on correctly prepared grooved ends. Both connection surfaces should be inspected before assembly.
The clamp uses a ductile iron housing that provides a durable two-piece body for compatible grooved piping applications. The housing sections surround the gasket and engage the grooves on both connected components when the assembly is secured.
Inspect both housing halves before installation for cracks, deformation, corrosion, contamination, or damaged groove-engagement surfaces. Damaged components should be replaced rather than installed into the piping system.
The L03BU includes a nitrile rubber gasket that forms the sealing element between the two compatible grooved pipe ends. The gasket should remain properly positioned around the joint while the two housing sections are assembled around it.
Inspect the gasket for cuts, hardening, swelling, flattening, contamination, or other deterioration before installation. Confirm nitrile compatibility with the intended media and operating conditions before placing the connection into service.
The two-piece housing allows the clamp sections to be positioned around the gasket and properly prepared grooved components during assembly. The housing should seat evenly around both pipe grooves before the fasteners are completely secured.
Verify nominal size, pipe OD, groove condition, gasket material, housing condition, and mating components before installation. Correct component selection and proper assembly help maintain the intended grooved connection throughout service.
Installation & Selection Considerations
Confirm the 3" nominal size.
Verify the 3.500" pipe OD.
Inspect the nitrile gasket.
Check both pipe grooves.
Verify housing engagement.

Our product specialists can help review nominal size, pipe OD, gasket material, grooved connection requirements, and mating component compatibility before you order.
