Feekoon 3 Pcs Ground Clamp 1/2″ To 1″

Overview: This set includes three ground clamps, each with fixing screws. Designed to fit 1/2″ through 1″ pipes and copper rods, these clamps support wires from #10 to #2. Bronze copper alloy provides strong conductivity and corrosion resistance, aiding durable grounding connections for gas line safety. Tightening should be snug but not excessive to avoid pipe damage.
Why it’s suitable for gas line applications: The clamps’ broad pipe range and robust material improve reliability on metallic gas lines and nearby conduits. The included screws streamline installation, reducing inspection time and potential miscounts on site. The bronze alloy delivers dependable conductivity and long-term resistance to environmental elements.
Installation considerations: Ensure clean, bare metal on the pipe at the clamp contact. Avoid overtightening, which can deform or crack pipes. If used alongside other grounding components, verify compatibility with your local electrical codes and bonding requirements.
Southwire Bronze Grounding Clamp

Overview: This clamp connects copper ground wire to water pipes, copper tubing, or ground rods. It features an integrated lay-in lug for fast installation and supports direct burial scenarios. It is suitable for 1/2″ to 1″ pipes and 3/8″ to 1″ rods, with a wire range of #10 SOL to #2 STR. The design emphasizes quick, secure bonds in residential and commercial settings.
Why it’s suitable for gas line applications: Its integrated lug and broad compatibility help ensure a dependable bond to metal gas lines and nearby grounding paths. The bronze construction resists corrosion, important for outdoor gas line installations or damp environments.
Installation considerations: Use the lay-in lug to simplify wire threading. Verify that the wire gauge matches the clamp’s rated range and keep wiring under the clamp’s clamp area to prevent exposure. Follow local electrical codes for gas line bonding requirements.
COREX 1/2″ to 1″ Bronze Ground Clamp

Overview: This bronze ground clamp supports pipe ranges from 1/2″ to 1″ with a wide wire range of #10 through #6. The bronze construction provides high conductivity and durability for grounding gas lines and associated piping systems. It is built to withstand typical on-site conditions and install with standard hardware.
Why it’s suitable for gas line applications: Bronze clamps offer stable electrical performance on metallic gas lines and resist corrosion when exposed to moisture or soil contact around outdoor piping. The clamp’s range accommodates many common bonding scenarios.
Installation considerations: Confirm pipe size before installation. Clean contact surfaces to ensure a solid electrical path. Do not exceed recommended torque on screws to avoid damaging the pipe.
SIGMA ProConnex 41309 Ground Clamp

Overview: Made from copper alloy with zinc-plated steel screws for long-lasting performance, this clamp ensures reliable grounding for equipment and gas line systems. It is designed to fit pipes or copper rods from 1/2″ to 1″, supports wires from #10 to #2, and accommodates rebar from 5/8″ to 3/4″.
Why it’s suitable for gas line applications: The copper alloy construction promotes strong conductivity and stable electrical bonds. The inclusion of compatible sizes broadens its use across various gas line bonding scenarios, including older installations with copper rods or galvanized components.
Installation considerations: Check for proper alignment with the pipe and secure mounting. If rebar or alternative grounding paths are used, ensure compatibility and code compliance for industrial or residential gas line bonding requirements.
SIGMA ProConnex 41409 Ground Clamp Conduit Fitting

Overview: This clamp is designed for 1/2″ to 1″ pipe or copper rod and supports wire ranges suitable for typical grounding tasks. It also functions as a conduit fitting for armored wire, expanding its versatility in wiring and grounding applications beyond standard piping.
Why it’s suitable for gas line applications: The flexibility to work with armored wire and copper paths provides practical options for bonding gas lines in complex electrical installations or older properties with varied wiring systems.
Installation considerations: When used with armored wire, ensure proper protection against abrasion and secure routing to avoid exposed conductors. Confirm that the clamp’s standards align with local codes for gas line bonding.
Sigma ProConnex 49160 Zinc Ground Clamp

Overview: This zinc-coated clamp connects bare insulated copper wire to galvanized steel water pipes and supports 1/2″ to 1″ pipes or copper rods. It handles wires from #10 to #2 copper, making it suitable for a range of grounding configurations in gas line systems and surrounding infrastructure.
Why it’s suitable for gas line applications: Zinc coating adds corrosion resistance in outdoor or humid environments, helping maintain a stable low-impedance path for grounding. The clamp’s compatibility with multiple pipe sizes makes it adaptable for different property layouts.
Installation considerations: Prepare clean contact surfaces and ensure a tight but controlled fastening to avoid bending the pipe. Verify the grounding path remains protected from physical damage and complies with local bonding rules.
Buying Guide: Key Considerations For Gas Line Grounding Clamps
- Pipe and wire compatibility: Match the clamp’s pipe range (commonly 1/2″–1″ or 1-1/4″–2″) and wire range (#10–#2, etc.) to your gas line and bonding wire specifications.
- Material and corrosion resistance: Bronze and copper alloy clamps offer strong conductivity and corrosion resistance, valuable for outdoor or damp environments around gas lines.
- Installation ease: Look for clamps with integrated lugs or screws, and ensure you can achieve a reliable bond without over-tightening, which can damage pipes.
- Code compliance: Verify that the clamp type and bonding method meet local electrical and gas line bonding codes. Some regions prescribe specific clamps or installation practices for gas piping systems.
- Durability and long-term performance: Consider clamps designed for long service life, especially in outdoor or underground installations where moisture and soil exposure occur.
- Versatility: Some models double as conduit fittings or accommodate armored wiring, offering flexibility for existing or mixed systems.
