Norgren D0LC0400 Pneufit D Push-in Fitting - NSF Certified
Part Number: D0LC0400
Quick Summary
D0LC0400 Pneufit D push-in fittings provide reliable, quick-connecting fluid paths for pneumatic and liquid lines in compact automation equipment. Engineers often struggle with secure connections that are easy to assemble, compatible with multiple tube materials, and compliant with cleanability requirements. This family features FDA-approved acetal, NSF 51/61 certified, and EC 1935/2004 MOCA certified for food-contact applications. For food-grade systems and sanitary equipment, D0LC0400 delivers hygiene, reliability, and reduced downtime across 4 mm tubing. This combination of materials, certifications, and a locking clip supports compliant assembly in regulated sectors such as food processing and medical analytics. Its 4 mm O/D size simplifies integration with compact manifolds and air logic modules, lowering inventory and spare parts.

4 mm O/D tubing compatibility provides a secure, leak-resistant connection. The releasable stainless-steel grab-ring grips nylon, polyurethane, or polyethylene tubing, while the locking clip speeds assembly and reduces the risk of accidental detachment. In practice, this means faster line setup and fewer reworks on the shop floor. Body made from FDA-approved acetal with EPDM seals offers chemical resistance for food and beverage, water, medical and analytical equipment. This material combination supports cleanability and regulatory alignment, improving audit readiness and reducing contamination risk. The design is MOCA-certified and EC 1935/2004-compliant, reinforcing confidence in regulated environments. Operating temperature range of -20 to 98 C and operating pressure from -0.9 to 20 bar enable use across a broad spectrum of fluids and air applications. The 4 mm size aligns with common small-bore tubing used in compact automation, enabling predictable performance and compatibility with Pneufit D families. Installation is straightforward alongside existing Pneufit components, reducing spare parts inventory. In vibration-rich environments, the locking clip and releasable grab-ring deliver reliable performance and minimize downtime.

FAQs
To install, cut the tubing square and insert into the D0LC0400 until the stainless-steel grab-ring engages. Ensure the locking clip is fully seated to prevent accidental release. This tool-free method minimizes setup time and reduces the chance of leaks, especially on busy production lines using 4 mm O/D tubing.
The D0LC0400 supports nylon, polyurethane, and polyethylene tubing with a 4 mm outer diameter. The releasable grab-ring provides secure retention across these materials, while the EPDM seals offer reliable chemical resistance for pneumatic and light liquid applications in food, water, medical, and analytical equipment.
The fitting operates from -20 to 98 C (-4 to 208 F) and supports pressures from -0.9 to 20 bar (-14.5 to 290 psi). This broad range makes it suitable for diverse process environments, including high-humidity sanitary lines and compact automation circuits, without sacrificing performance or reliability.
The D0LC0400 uses FDA-approved acetal, and is NSF 51/61 certified, MOCA certified, and EC 1935/2004 compliant. These certifications ensure suitability for food-contact applications, regulatory compliance for sanitary design, and reduced risk during audits—critical factors for food and beverage, medical, and analytical industries.
The push-in design with a locking clip minimizes installation time, while the grab-ring provides robust retention in vibration-prone lines, reducing leak-related downtime. Its durable materials and certifications also lower maintenance costs and spare-part inventory, supporting predictable performance and quicker line changes across production runs.
