SMC KQ2T03-00 5/32" Push-In T-Connector Quick Connect Air Fitting | PVA Compatible
SMC KQ2T03-00 — 5/32" Push-In Union T-Connector, Quick Connect Air Fitting (PVA Compatible)
Note: The KQ2T03-00 is a discontinued legacy part number. It has been officially replaced by the fully compatible active part number KQ2T03-00A, which maintains identical 5/32" push-to-connect dimensions and 145 PSI rating. Orders may ship as KQ2T03-00A — contact MTE Solutions to confirm availability.
The SMC KQ2T03-00 is a 5/32" tube OD push-in equal union T-connector from SMC Corporation's KQ2 Series One-Touch Pneumatic Fittings. SMC is the manufacturer; this fitting is commonly referenced in PVA fluid dispensing and selective conformal coating system Bills of Materials (BOMs) and schematics, where PVA specifies SMC KQ2 series fittings for their internal pneumatic plumbing. The PBT body provides chemical and temperature resistance suitable for industrial dispensing environments. Tool-free push-in connection and one-touch release make it ideal for maintenance and system assembly.

Frequently Asked Questions
Is the KQ2T03-00 still available?
The KQ2T03-00 has been officially discontinued by SMC Corporation. The direct replacement is the KQ2T03-00A, which is identical in tube OD, pressure rating, and dimensions and is widely available through industrial distributors. Contact MTE Solutions to confirm which part number will be shipped for your order.
Is the KQ2T03-00A a direct drop-in replacement?
Yes — the KQ2T03-00A is fully compatible with the KQ2T03-00. It maintains the same 5/32" push-to-connect dimensions and 145 PSI maximum working pressure. The only visible differences are the white release button (vs. orange) and an updated body design. No modifications to tubing or system plumbing are required.
What is the maximum working pressure for this fitting?
The KQ2T03-00 / KQ2T03-00A is rated for a maximum working pressure of 145 PSI, suitable for standard compressed air lines used in PVA dispensing systems and general industrial pneumatic applications.
Why does my PVA system BOM list KQ2T03-00 if PVA doesn't make it?
PVA (Precision Valve & Automation) is an OEM integrator — they design and build automated fluid dispensing and conformal coating systems using components sourced from industrial suppliers including SMC Corporation. PVA's system BOMs and schematics reference the raw SMC manufacturer part numbers directly, which is why KQ2T03-00 appears in PVA documentation. The fitting itself is an SMC product.
What body material is the KQ2T03-00 made from?
The KQ2T03-00 / KQ2T03-00A body is made from PBT (polybutylene terephthalate), a thermoplastic with good chemical resistance and temperature stability suitable for industrial pneumatic applications.
