Frequently asked questions
Common questions about OETIKER from 3G Electric.
What is the difference between the OETIKER ratchet pincer models 14100280-GRA and 14100069-GRA?
The primary difference is clamping force. Model 14100280-GRA is rated at 1,574 lb, while model 14100069-GRA is rated at 495 lb. Both are steel ratchet pincers that include a GO-NO GO gauge and accommodate wire sizes from 0.375 in to 1 in. The higher-force model is suited for larger diameter clamps or applications requiring greater compression, whereas the lower-force model is adequate for standard PEX tubing connections. Choose based on the clamp size and material thickness in your system.
Does the OETIKER clamp tool SKU 4E607 (MPN 14100396) include a GO-NO GO gauge?
No, the OETIKER clamp tool SKU 4E607 (MPN 14100396) does not include a GO-NO GO gauge. It is a manual clamp tool made of forged steel with a clamping force of 530 lb. It is designed for use with OETIKER ear clamps in sizes 3/8 in, 1/2 in, 5/8 in, 3/4 in, and 1 in. For verification of proper closure, you would need a separate gauge or rely on visual inspection per manufacturer guidelines.
What materials are OETIKER PEX ear clamping tools made from?
OETIKER PEX ear clamping tools are constructed from steel or forged steel. The ratchet pincer models (e.g., 14100280-GRA and 14100069-GRA) use steel, while the manual clamp tool (MPN 14100396) uses forged steel. These materials provide the strength and durability needed for repeated crimping operations without deformation, ensuring consistent clamp closure over the tool's service life.
Can OETIKER ear clamping tools be used with non-OETIKER ear clamps?
OETIKER ear clamping tools are designed specifically for OETIKER ear clamps to ensure proper compression and joint integrity. While they may physically fit other brands of ear clamps, the GO-NO GO gauge included with ratchet pincers is calibrated to OETIKER’s clamp ear height specifications. Using them with non-OETIKER clamps may result in incorrect closure, leading to leaks or clamp failure. For reliable performance, use OETIKER tools with OETIKER clamps.
What is the purpose of the GO-NO GO gauge included with OETIKER ratchet pincers?
The GO-NO GO gauge is a quality control tool that verifies the ear of an OETIKER ear clamp has been compressed to the correct height after crimping. The gauge has two slots: a GO slot that the compressed ear should pass through and a NO GO slot that it should not. If the ear fits the GO slot but not the NO GO slot, the clamp is properly closed. This ensures consistent, leak-proof connections and reduces the risk of under- or over-crimping.
What is the maximum compatible wire size for OETIKER ratchet pincers?
Both OETIKER ratchet pincer models (14100280-GRA and 14100069-GRA) have a maximum compatible wire size of 1 in and a minimum of 0.375 in. This range covers common PEX tubing diameters used in residential and commercial plumbing systems. The manual clamp tool (MPN 14100396) accommodates sizes from 3/8 in to 1 in, providing similar coverage for ear clamp installation.
