ASAB 1/4" Nitto F–M Fitting (Double Diaphragm Air Connect)

Part Code: ASAB-F-N1/4FM

Introducing the ASAB 1/4" Nitto Fitting — a job-site-ready quick-connect adaptor designed to make air line hook-ups fast, tidy, and reliable on double diaphragm pumps and other pneumatic equipment. Built around the popular Nitto-style quick connect, this fitting lets you connect/disconnect air supply lines quickly while maintaining a secure, leak-resistant connection.

With a 1/4" Female x 1/4" Male configuration, it’s ideal for adapting between common air fittings and pump air inlets, air service manifolds, or hose whip lines. Whether you’re setting up a new air supply line, replacing a worn coupler adaptor, or standardising your diaphragm pump fleet on Nitto connections, the ASAB-F-N1/4FM is a simple upgrade that saves time and reduces mucking around with spanners.

Safety Check

• Isolate and depressurise air supply first: Shut off air, bleed the line fully, and confirm pressure is at zero before changing fittings.

• Confirm Nitto profile match: Nitto-style quick connects come in different series—ensure the mating plug/coupler is the same profile (don’t force mismatched types).

• Confirm thread type before install: Check whether your equipment is BSP vs NPT and match accordingly (mixing threads = leaks/stripped ports).

• Use correct sealing method: Apply thread sealant/tape only where appropriate and keep it off the first thread to avoid contamination.

• Leak check safely: Pressurise slowly and use soapy water—don’t check leaks with your hands near pressurised joints.
