Overview

Note: The fittings are sold individually and not in pair. Brass Poly Flo fittings cannot be used with NSR tubing listed. Use SAE fittings, see Accessories tab.

I am not impressed. Once tightened it is difficult to untighten or tighten the nut with out twisting the Nylaflow tubing. The old style that used a feral in the Nylaflow tubing is amuch better design.

These brass fittings are smaller than the plastic ones, and clamp onto the tubing much better. Made the pitostatic install very nice.

Q&A

Please note, Aircraft Spruce's personnel are not certified aircraft mechanics and can only provide general support and ideas, which should not be relied upon or implemented in lieu of consulting an A&P or other qualified technician. Aircraft Spruce assumes no responsibility or liability for any issue or problem which may arise from any repair, modification or other work done from this knowledge base. Any product eligibility information provided here is based on general application guides and we recommend always referring to your specific aircraft parts manual, the parts manufacturer or consulting with a qualified mechanic.

Q: Are these fittings reusable?

These can be re-used but they should be inspected before doing so. If there is damage to the fitting it should be replaced. It is at the discretion of the installer whether it should be replaced or not. We cannot, as a blanket statement, say they can all be reused.

Q: How should the brass Poly-Fittings assembled with the Nyla-Flow Tubing? What is the requirement for tighten them only finger tight? How is it ensured that once tightened it will not become loose and might leak?

You insert the tube into the nut and then tighten the nut on to the fitting. The vendor tightening spec is "finger tight, plus a 1/4 turn with a wrench."

Q: Can you provide the part no for these nuts with the nylon sleeves?

That would be the 268 model. Those have nylon inserts on the nuts on them.
