Our Story

More than 30 years ago, our founder started NSL with a plan: source precisely what customers wanted, work fast, and always provide the best possible service. John Hunter started this company with those big ambitions and a fierce determination to succeed. So much has changed since then among companies that sell aerospace sealant. But for us, an entrepreneurial spirit and focus on core values is still our foundation in 2023.

Our top priority is taking care of our customers. That’s why we offer so many extra services – the “one-and-done” business model isn’t for us. Every day, we work personally with customers around the world to answer technical product questions, help with sealant selection, handle urgent orders, and more. Need custom packaging or a quick turnaround? We’ve got you covered. Your repeat business is the highest compliment.

We also believe in treating employees with respect, and it shows. Many NSL Aerospace employees have worked here for years – over a decade for several! We’re proud of our retention rate, because it means our employees are happy. We believe happy employees create happy customers.

We’re also committed to high-quality work. We maintain AS 9100D and ISO 9001:2015 certifications, as well as Nadcap accreditation. To do this, industry experts regularly inspect our Houston-area facilities to certify compliance. Additionally, we created an on-site lab that does its own testing. This means double quality checks, which distinguishes us as a distributor that is deeply committed to product standards and safety.

We value kindness and compassion for our fellow human beings and animals, as well as the environment. We follow safe and responsible practices and procedures that keep our world and each other healthy and secure. We also support multiple nonprofits in Houston and internationally. Those include Wounded Warrior Project, Houston Food Bank, the Smile Train, and Habitat for Humanity.

We want to earn your business and keep it. Get in touch today for a quote, to get more information about an aerospace sealant, or just to say hello.
