Product Description

The SMC High Purity Tube Fitting (MPN LQ3U4A-R2) is a PFA compression x compression fitting for 1/2 in OD x 1/4 in OD tubing, part of the LQ3 series. It meets RoHS_6 and RoHS_10 standards, supporting clean fluid handling in industrial applications.

Frequently Asked Questions

What is the SMC LQ3U4A-R2 high purity tube fitting used for?

The SMC LQ3U4A-R2 is a PFA compression fitting used to connect 1/2 in OD to 1/4 in OD tubing in clean fluid handling systems. It is common in semiconductor, pharmaceutical, and chemical processing applications where purity and corrosion resistance are critical.

What are the specifications of the SMC LQ3U4A-R2 fitting?

The SMC LQ3U4A-R2 is a compression x compression PFA fitting from the LQ3 series. It connects 1/2 in OD to 1/4 in OD tubing and meets RoHS_6 and RoHS_10 standards. The manufacturer part number is LQ3U4A-R2.

Where to buy the SMC LQ3U4A-R2 fitting worldwide?

3G Electric supplies the SMC LQ3U4A-R2 high purity tube fitting to customers worldwide. We handle full logistics, customs clearance, and delivery, ensuring you receive genuine SMC components for your clean fluid systems.

How to install the SMC LQ3U4A-R2 PFA compression fitting?

To install the SMC LQ3U4A-R2, cut tubing squarely, deburr, and fully insert into the fitting. Tighten the nut finger-tight, then use a wrench for the recommended turns. Avoid over-tightening to prevent PFA creep. Always follow SMC's installation guide for the LQ3 series.
