SS316 Push-In Fittings – SP Series
The SS316 Push-In fittings from the POOLKE SP Series are designed for pneumatic and fluid systems that require higher corrosion resistance, reliable tube retention and convenient installation. Manufactured in SUS316 stainless steel, this series is particularly suitable for demanding industrial environments where standard brass fittings may not provide sufficient resistance to moisture, chemicals or corrosive media.
The push-in connection structure allows tubing to be installed quickly without special assembly tools. Tubes can also be removed by operating the release mechanism, making maintenance and piping modifications more efficient. A full-flow internal passage helps maintain smooth media transfer, while the compact fitting design supports installation in space-limited machinery and process equipment. Available for metric and inch tubing together with several international thread standards, the SS316 Push-In fittings provide a versatile connection solution for pneumatic automation, process systems and industrial fluid lines requiring durable stainless steel components. The catalog identifies SP as the SUS316 version within the push-in fitting range.
