Part Number: D22250418
Quick Summary
Norgren D21250638 Pneufit D Adaptor is a push-in fitting for quick, secure tubing connections in compressed air and liquids. Many installations struggle with leaks, compatibility issues, and slow assembly when upgrading lines in harsh environments. Constructed from FDA-approved acetal and certified to NSF 51/61 and MOCA, it also complies with EC 1935/2004 for food-contact materials. With a straight R3/8 port, 3/8 inch tubing options, and a releasable stainless-steel grab-ring, it supports rapid field changes and reduced downtime. Designed for food-grade and analytical environments, it also handles water and medical equipment, delivering a leak-tight connection that resists chemical attack. The broad operating range of -20 to 98 °C and -0.9 to 16 bar supports reliable performance across plants, labs, and process lines.

FAQs
D21250638 is a straight push-in adaptor with a 3/8" tubing interface and R3/8 thread, designed for rapid, secure connections. It fits standard 3/8" tubing in compressed air and many liquids, and its acetal body paired with EPDM seals offers robust chemical resistance. When upgrading legacy connections, ensure the tubing material is compatible with acetal bodies to maintain seal integrity.
This adaptor carries NSF 51 and NSF 61 certifications and MOCA certification, along with EC 1935/2004 compliance for food-contact materials. These certifications matter because they validate suitability for food and beverage, medical, and analytical applications, ensuring safe contact with consumables and compliant performance in regulated environments.
Yes. The body is made from FDA-approved acetal and the fitting is NSF 51/61 certified with MOCA certification, aligning with food-contact material regulations. EPDM seals provide chemical compatibility, and the assembly supports clean-in-place/sterilization cycles common in hygienic and beverage equipment without compromising seal integrity.
The releasable stainless-steel grab-ring enables tool-free removal and quick disassembly of tubing, reducing service time in field maintenance. This feature minimizes downtime during tubing replacements or line reconfigurations, which is especially important in high-mix manufacturing, clean rooms, and medical device assembly lines.
Consider a temperature range of -20 to 98 °C and a pressure range of -0.9 to 16 bar, which covers most pneumatic and light-liquid circuits. Port size is R3/8 with straight geometry, supporting standard 3/8" tubing. The acetal body with EPDM seals provides broad chemical compatibility, making it suitable for food-grade, water, and analytical applications.
