We’re excited to welcome new National Aerospace/Manufacturing Product Manager, Diane Swencki, to our team at Brennan. She will be working out of Brennan’s manufacturing facility in Euclid, Ohio.

Both flared and flareless fittings are commonly used in the aerospace industry, depending on the application. The AN (Army-Navy) military standard calls for tighter tolerances and defines all fitting types, where the JIC uses AN specifications as the base line for their own standards and covers fewer sizes. 

In the aerospace industry,  O-rings are very popular among equipment designers because of their leak-tight connections, typically using a 90 durometer, Buna-N (Nitrile) O-ring. There are two primary types of O-ring boss fittings:

Fitting Types

In the aerospace industry,  sections of tubing are usually attached with flared or flareless (compression type) fittings, unlike steel pipe. The SAE Aerospace Standard (AS) establishes the requirements for fittings that are used in all types of fluid systems. 

Manufacturers of fluid system fittings for the Aviation, Space, and Defense industries must meet very stringent requirements. 

This includes the production of specialty fittings and machined parts.  Aerospace Standard (AS) AS7112, in accordance with SAE AS7003, establishes the requirements for manufacturers of fluid system components to be accredited by Nadcap (National Aerospace and Defense Contractors Accreditation Program). 

If you or your customers use fittings in aerospace applications, then you know you're limited to only those manufacturers meeting stringent quality requirements and certifications. We are excited to announce you have a new choice - Brennan!
