R134a Quick Couplers<\/h3>

QC-L \/ QC-H<\/strong><\/p>

This series offers a red QC-H high-pressure coupler and a blue QC-L low-pressure coupler. Optional 1\/4" SAE and M14\u00d71.5 adapter configurations are available, so the adapter requirement should be specified together with the coupler model.<\/p>

Choose this series when sourcing the pictured standard coupler style with an optional adapter. Each listed version is packed at 120 pieces per carton. State the required quantity for the red and blue versions separately in your inquiry.<\/p>

Connection:<\/strong> Optional 1\/4" SAE & M14\u00d71.5 adapter
Options:<\/strong> High Pressure (Red) \/ Low Pressure (Blue)
Packing:<\/strong> 120 pcs\/ctn<\/p><\/div>

\"QC-LC<\/a><\/figure>

Adjustable Extended R134a Quick Couplers<\/h3>

QC-LC \/ QC-HC<\/strong><\/p>

The adjustable extended series provides an alternative body style to the standard models. QC-HC identifies the red high-pressure version, while QC-LC identifies the blue low-pressure version. The listed connection specifications are 1\/4" SAE and M14\u00d71.5.<\/p>

When selecting this configuration, confirm the available installation space and required connection with your equipment specification. Packing is 120 pieces per carton for each version. Include the model and connection requirement when requesting a quotation.<\/p>

Connection:<\/strong> 1\/4" SAE & M14\u00d71.5
Options:<\/strong> High Pressure (Red) \/ Low Pressure (Blue)

\"QC-12L<\/a><\/figure>

1\/4" SAE R134a Quick Couplers<\/h3>

QC-12L \/ QC-12H<\/strong><\/p>

QC-12H and QC-12L are the pictured R134a quick coupler models with a 1\/4" SAE connection. The red QC-12H is the high-pressure version, and the blue QC-12L is the low-pressure version.<\/p>

This series has a listed packing quantity of 240 pieces per carton for each version, compared with 120 pieces per carton for the other three series. This difference is useful when preparing carton-based purchasing quantities and comparing packing arrangements.<\/p>

Connection:<\/strong> 1\/4" SAE

How to Select Your R134a Quick Coupler<\/h2>

1. Select the pressure side.<\/strong> Choose the red high-pressure or blue low-pressure model from the required series. The labels identify the product version; the table does not specify a numerical working-pressure rating.<\/p>

2. Confirm the connection.<\/strong> Match the listed 1\/4" SAE or M14\u00d71.5 requirement to your equipment. For QC-H \/ QC-L, specify whether the optional adapter is required. Send a connection photo or drawing if you need help identifying the configuration.<\/p>

3. Choose the body style.<\/strong> Compare the standard, adjustable extended and 90\u00b0 options against your required layout. If exact overall dimensions are needed, include them in your inquiry so the model can be confirmed before ordering.<\/p>

4. Plan the order quantity.<\/strong> QC-12H \/ QC-12L are listed at 240 pcs\/ctn; the other series are listed at 120 pcs\/ctn. PCS\/CTN describes the packing quantity, not a stated minimum order quantity.<\/p>

Ordering Information<\/h2>

Please specify the model, high-pressure or low-pressure version, connection or adapter requirement, order quantity and destination. For QC-H \/ QC-L, indicate whether the optional adapter is required.<\/p>
