FAQs
Yes. The Pneufit D uses a releasable stainless-steel grab-ring that secures nylon, polyurethane, or polyethylene tubing, delivering reliable grip and quick release. It supports 1/4" and 3/8" tubing with a union elbow to steel tube, and Norgren offers compatible PE tubing options for a seamless install.
The fitting operates from -20 to 98 °C and -0.9 to 16 bar (-14.5 to 232 psi). This broad range supports varied fluids and conditions, helping keep systems stable and reducing the risk of leaks across both pneumatic and liquid circuits.
Yes. The body is made from FDA-approved acetal with EPDM seals, and the part carries NSF 51/61 certifications along with EC 1935/2004 MOCA compliance. These credentials support food-contact applications and regulated environments such as beverage processing, medical devices, and analytical equipment.
Ensure proper tubing preparation with clean, square cuts and the correct 1/4" or 3/8" size. Insert tubing firmly into the grab-ring until it seats, then test pressure gradually. Use compatible tubing from the PE series, and verify the union elbow alignment to steel tubing for a leak-free seal.
Benefits include reduced downtime from quick connect/disconnect and lower maintenance costs due to reliable materials (FDA acetal, NSF/MOCA certified). The stainless grab-ring design minimizes wear, while standardization within the Pneufit D range simplifies stocking and procurement, delivering faster project timelines and predictable total cost of ownership.
