Flangeless Nut Extender Tools

Use the P-298, P-299 or P-399 Extender Tool to tighten any standard, short or extra long style nut in hard-to-reach places. For our Headless nuts, try the P-297 Tool. These tools can tighten any Upchurch Scientific knurl-headed male nut (except F-287, F-288 and winged nuts). They can also be used with many of the low pressure nuts. The F-346 Tool tightens FlushNut™ Fittings.

Ultra High Performance version of a Super Flangeless Fitting is available.
