PPE is a AS9100 Rev.B certified designer and manufacturer of elastomer products, with a dedicated aerospace manufacturing cell providing O-rings, custom mouldings and high performance seal geometries to the entire aerospace supply chain.
We hold many prime contractor and OEM quality approvals and our short lead-time makes us an ideal partner for Maintenance Repair and Overhaul (MRO) operations, where we can quickly react to aircraft on ground (AOG) situations.
We recommend the use of SAE standards AS568 / AS4716 for O-ring and groove dimensioning, which are available to purchase at www.sae.org, alternatively PPE groove dimensions can be downloaded here.
