For an equipment replacement or a new installation, match the complete part designation to the actual connection and mounting drawing. The checkpoints below help specify the quoted variant without assuming unlisted performance values.






These are selection inputs, not unverified technical ratings. Request the current model drawing and confirm any missing values before ordering.
| Selection check | Information to confirm |
|---|---|
| Panel dimensions | Provide mounting-hole size, panel thickness and access to both sides of the panel. |
| Union interfaces | Confirm the tube sizes and connection style on each side of the union. |
| Mechanical support | Plan independent support for tubing so panel mounting does not impose side loads on the connection. |
| Assembly clearance | Allow space for the mounting hardware, tools and tube release operation. |
Provide the panel thickness, mounting-hole dimensions and tube sizes on both sides when selecting the bulkhead union. Treat the quoted model and interfaces as the starting point for a replacement or new-build enquiry.
Oulu presents pneumatic fittings alongside its microduct and fiber-installation products. Its About Us page describes size matching, sample evaluation, quality inspection and packaging support. Confirm which services apply to the selected product and order.

Prepare a specification-led enquiry for samples, replacement stock or an equipment build. The Oulu service page describes consultation, packaging, delivery and after-sales support.
Choose by tube outside diameter, tube material, port interface and working conditions. A brand or series name is not a substitute for the correct dimensional match.
Leakage can result from damaged or incorrectly sized tubing, an incomplete connection or unsuitable service conditions. Request the installation method and leakage-test conditions for the selected variant.
Vacuum compatibility must be confirmed for the exact fitting and seals. A compressed-air listing does not by itself establish a vacuum rating.
Provide the panel thickness, mounting-hole dimensions and tube sizes on both sides when selecting the bulkhead union.
Request the exact drawing, connection or mounting dimensions, material and operating limits for the quoted code. Values for a similar series are not a substitute for the selected product.
Include the complete model, required size or interfaces, application, operating conditions, quantity and packing needs. Ask for samples and technical documents where needed, and confirm price, order quantity and delivery timing in the quotation.
