The Pneufit D D21250428 uses an acetal body, delivering excellent chemical resistance and food-contact suitability for demanding environments. FDA-approved materials, NSF certifications (51 & 61), and MOCA/EC 1935/2004 compliance help you meet stringent regulatory requirements without compromising performance. EPDM seals enhance compatibility with air and liquids while maintaining a tight seal through repeated cycles. A releasable stainless-steel grab-ring enables quick tubing release from nylon, polyurethane, or polyethylene hoses, reducing maintenance time and field downtime. The 1/4 inch port size with R1/4 thread and straight configuration simplify integration into standard pneumatic manifolds and compact enclosures, while minimizing vibration-induced leaks for long-term reliability. The range supports broad operating conditions (-20 to 98 °C, -0.9 to 20 bar) and accommodates both compressed air and compatible liquids, making it suitable for CIP-ready lines and sanitary process automation. Available tubing variants and the D2125 range provide flexible deployment in water, food, and analytical systems, enabling streamlined sourcing and predictable performance across projects. This combination lowers lifecycle costs by reducing part variety and enabling scalable, compliant designs across production assets.

FAQs
The D21250428 uses a 1/4 inch port size with an R1/4 thread and a straight configuration, designed to accept standard 1/4 inch nylon, polyurethane, or polyethylene tubing. Its simple push-in action and grab-ring allow quick, reliable connections without specialized tools, making it ideal for compact installations and fast changeovers.
Yes. The fitting uses a FDA-approved acetal body and carries NSF certifications (51 & 61) along with EC 1935/2004 MOCA compliance. These attributes ensure safe contact with food and compliant operation in medical and analytical environments, supporting cleanability and regulatory alignment across global facilities.
Operating temperature ranges from -20 to 98 °C (-4 to 208 °F) and operating pressure from -0.9 to 20 bar (-14.5 to 290 psi). This broad tolerance accommodates both compressed air and compatible liquids, enabling use in diverse automation processes without over-specifying parts.
Installation is quick due to the push-in design and the releasable stainless-steel grab-ring, which simplifies tubing changes. Compatibility with nylon, polyurethane, or polyethylene tubing reduces stocking complexity, while the robust R1/4 thread and straight profile help minimize leaks and maintenance downtime in high-cycle environments.
The fitting holds NSF 51 & 61 certifications, FDA-approved acetal body, MOCA certification, and EC 1935/2004 compliance. These certifications verify material safety, food-contact suitability, and regulatory alignment, reducing risk during audits and ensuring safer, compliant system designs across industries.
