Superlok Testimonials

What Our Customers Are Saying About Superlok i-Fitting Products,

“It’s been 1-1/2 years since we started using Superlok fittings supplied by Mako Products. We are a true believer in the Superlok fittings. They have cut down on installation time and cost associated with high pressure stainless steel tube fittings. When it comes to service, the (Mako) team is quick to respond to RFQ’s, usually within a couple of hours – not a couple of days like some of the competition. Delivery is spot on and efficient, also. I also enjoy the newsletters Mako puts out with current events.

I would like to personally thank the Mako team for the professional attention to detail that is supplied.”

Darren, LouisianaProduction / Product Manager

“I’m in love with the breakaway indicators. Gauging was guesswork at best.”

Randy, Pennsylvania

“We used another brand of tubing fittings for over 20 years before changing to the Superlok i-Fitting line. We’ve found that the fittings are interchangeable with the other brand, so integration issues are non-existent. Although our previous brand had no quality issues, we are constantly looking for ways to reduce costs in a globally competitive business environment. The Superlok i-Fitting brand has helped us begin realizing savings without having to change the fittings that were previously installed.

We’re very satisfied with the Superlok i-Fittings.”

Jeff, AlabamaI/E Engineer

“Can’t keep my fittings on my shelf!”

Mark, Colorado

“The Superlok i-Fitting has given us a superior product to offer the market. It’s helped solve safety, time and cost issues!”

TJ, TexasPurchasing Manager

“We were interested in doing business with a company that has both a great reputation and a great product backing it. The Red Ring (Superlok i-Fitting) prevents over and/or under tightening and has played a big part on the success of this product over others.”

Rebecca, TexasGeneral Manager

“This is a great product line. Our customers have had no complaints of the quality of the product and will continuously buy and stock.”

Sam, Texas

“The pricing is good on them, we have no problems! We use them in marine application in oil, fuel and seawater/saltwater.”

OceanPower Engineer

“We had problems with another brand of tube fittings leaking and since we’ve used Superlok, they are secure, pop-off at the right time and there’s no guesswork! I’m loving it. We don’t have any problems doubling back to have to check the fittings either.”

Patrick, TexasI/E Technician
