SUPERLOK FITTINGS: THE LEAK-FREE REVOLUTION IN INSTRUMENTATION AND CONTROL

THE SUPERLOK ADVANTAGE – GUARANTEED LEAK-FREE PERFORMANCE

We introduce an exciting and innovative line of instrumentation and control products designed for durability and guaranteed performance. Superlok fittings are high-end plumbing components, primarily made of high-grade stainless steel, suitable for high-pressure environments. While serving multiple markets, Superlok focuses strongly on the car wash industry, where our durable, lifetime-guaranteed products ensure your operations function well, reducing service calls, and maximizing profit (dollars in your pocket). Superlok is the premium brand under the parent company, Mako Products.

The Superlok fitting is considered a game changer in the industry and holds two patents that directly address the high leak rate problems commonly seen in standard tube fitting installation. Industry reports often show a 5% to 10% leak rate, not due to the fitting itself, but due to improper installation processes. Superlok was designed to solve this problem, aiming to bring that leak rate down to zero.

Key Innovations and Features

Patented Technology

The Red Ring Patent

Built-in Gap Gauge/Installation Indicator

Standard installation requires hand-tightening, marking the nut and body, and turning the nut one and one-quarter turns. This is followed by using a gap gauge—a step often missed by installers (less than 5% use one).
The Superlok system is an almost "dummy proof" leak-free guaranteed process.
The primary patent utilizes a red ring indicator that pops at the exact moment the nut is turned the required one and one-quarter times from hand tight. This indicator confirms the point of perfect compression.
The red rings are reusable and can be snapped back on, acting as a portable gap gauge.

The Blue Identification Band Patent

Secondary Visual Confirmation

Superlok has the only color change system in the market.
When the fitting has been tightened correctly, the blue band is visible.
This provides a crucial secondary visual confirmation. If red rings are still visible in an assembly of fittings, installers can immediately identify that the fitting was not tightened, helping to prevent safety issues and ensuring a leak-free assembly before leaving the facility.

Quality and Logistics

Quality	Fittings are individually bagged to maintain cleanliness, prevent the loss of nuts and ferrules during handling, and clearly display the part number and size for easy identification, especially for inexperienced users.
Ferrule System	We offer both double ferrule (typically recommended as a better sealing system, though single ferrules are available) and single ferrule systems.

Industry Focus: Car Wash Applications

The materials provided by Superlok, including stainless steel tube, MPT fittings, and JIC fittings, are highly utilized in the car wash industry.

Downtime is Dollar Loss	In the car wash industry, being down for an hour, two hours, or more translates directly to lost revenue. Using Superlok’s solid, guaranteed products, which prevent leaks and equipment failure, costs less in the long run than managing maintenance calls associated with subpar plumbing.
Material Compatibility	The 316 stainless steel material used in Superlok products is compatible with every chemical known to be used in the car wash industry. We recommend always using stainless steel with stainless steel to avoid galvanic corrosion that occurs with dissimilar metals (like stainless with brass).
Lifetime Product	Stainless steel tubing and fittings provide a lifetime product solution compared to rubber or poly hose, which can wear out.

Guarantees, Certifications, and Availability

Lifetime Warranty	Superlok provides a lifetime warranty against failure. To date, with millions and millions of fittings in the market over 13 years under this patent, we have not had a single warranty claim.
Interchangeability Guarantee	Our products are warranted to be 100% interchangeable and intermixible with the major competition (including Swedlock).
Certifications	We possess virtually every known certification in the market, including nuclear certification, and approvals from some of the world's largest companies.
Competitive Pricing	We are typically offered at a significant reduction in price compared to our biggest competitor, Swedlock.
Shipping & Inventory	We ship most products from Oklahoma City, centrally located in the US. Our commitment is same-day shipping if an order is placed by 4:30 PM Central. We maintain the largest inventory of instrumentation control products, including up to a million feet of tubing on the floor at all times.

Frequently Asked Questions

1. What is the key innovation of the Superlok tube fitting?	The Superlok fitting features a patented red ring indicator that visually confirms when the fitting has reached the exact point of perfect compression (one and one-quarter turns from hand-tight). This innovation effectively solves installation errors that traditionally lead to leaks.
2. Are Superlok fittings guaranteed to be leak-free?	Yes, Superlok offers a leak-free guaranteed process backed by a lifetime warranty against failure. Since holding this patent for 13 years, there has not been a single warranty claim filed despite millions of fittings being in the market.
3. What is the purpose of the blue identification band?	The blue identification band is a secondary visual confirmation that the fitting has been tightened correctly. If red rings are still visible after assembly, it indicates the fitting was not tightened yet, allowing installers to confirm a complete and leak-free installation.
4. Can I mix Superlok fittings and parts with those from other manufacturers (e.g., Swedlock)?	Yes. Superlok parts are certified and warranted to be 100% interchangeable and intermixible with the major competition.
5. What material is used in Superlok products, and is it compatible with car wash chemicals?	Superlok uses mostly high-grade stainless steel, specifically 316 stainless steel, which is compatible with every chemical known in the car wash industry.
6. What determines the maximum pressure rating of the system?	The pressure rating is determined by the specific tubing selected by the customer, based on its wall thickness, not the fitting itself. Fittings can handle extremely high pressure (30, 000 to 40, 000 PSI), while standard tubing may range from 2, 000 to 4, 000 PSI.
7. Where is the product manufactured?	This product is manufactured out of South Korea.
8. Can a fitting be reused or reconnected?	A fitting can be reconnected multiple times on the same tubing using the same ferrule, by tightening until a rise in torque is felt. However, the ferrules themselves are designed for one-time use. If you move the body and nut to a different location, you must use brand new ferrules. The red indicator rings are only required for the first time installation of the new ferrule onto the tube.
9. How quickly can I expect my order to ship?	Superlok (Mako Products) maintains a large inventory and commits to same-day shipping if the order is called in by 4:30 PM Central time.
