About this item

  • Superior Material for Longevity: Crafted from high-strength brass and engineering-grade PTC/PTCR polymers, these fittings resist corrosion and wear. This premium hybrid construction ensures a secure hold on nylon tubing, reduces maintenance needs, and delivers reliable performance even in low-temperature environments
  • Certified to FMVSS 571.106 Standards: Engineered to meet stringent DOT and SAE J2494-3 specifications. Designed for use with SAE J844 Type A/B nylon air brake tubing, each fitting is factory-tested for leaks to guarantee minimal pressure loss and maximum safety in critical air brake systems
  • Tool-Free Push-to-Connect Operation: Features a user-friendly release mechanism for fast assembly and disassembly. Simply insert the tube until it bottoms out and give it a tug to confirm secure engagement. To release, press the collet and pull the tube out—saving valuable time during maintenance or installation in tight spaces
  • Wide Application Range: Ideal for air brake systems on trucks and trailers, cab controls, air suspension, sliding rail systems, tire inflation, and auxiliary air lines on mobile equipment. Withstands extreme temperatures from -40°F to +200°F (-40°C to +93.3°C) and pressures up to 250 PSI
  • Factory Leak-Tested for Reliability: Every push-to-connect union undergoes rigorous individual airtightness testing before leaving the factory. We stand behind our quality—if you have any issues, our customer support team is ready to assist you promptly

FAQ

How can I confirm that a product is suitable for my application?


Review the product description, dimensions, materials, ratings, connection types, and compatibility information before ordering. Industrial requirements vary, so consult the equipment manufacturer or a qualified professional if you are uncertain.

Do you provide installation or technical advice?


We can help clarify information shown on a product page, but we do not provide engineering, installation, or workplace-safety advice. Products should be selected, installed, and operated by appropriately qualified personnel where required.

Can I change or cancel my order after placing it?


Contact us as soon as possible at ruleindgalein@gmail.com. We will try to accommodate your request, but changes or cancellations cannot be guaranteed once an order has entered processing or shipment.

When will my order be shipped?


Processing and delivery estimates may vary depending on the product, destination, inventory availability, and carrier. Please review the shipping information provided at checkout and our Shipping & Delivery Policy for additional details.

How can I track my order?


When tracking becomes available, it will be sent to the email address used for your order. Tracking activity may take some time to appear after the carrier receives the shipment.

Why did my order arrive in more than one package?


Items from the same order may be fulfilled or shipped separately. As a result, packages can arrive at different times and may have separate tracking numbers. You will not be charged additional shipping solely because an order is divided into multiple shipments.

What should I do if an item arrives damaged, defective, or incorrect?


Contact us promptly at ruleindgalein@gmail.com with your order number, a description of the issue, and clear photographs of the item, packaging, shipping label, and any visible damage. Keep all packaging until we provide further instructions.

Can I return an item if it is not suitable?


Eligible items may be returned in accordance with our Return & Refund Policy. Return conditions, exclusions, time limits, and any applicable costs depend on the item and circumstances. Please contact us before sending anything back.

Do you offer bulk quantities or business purchasing?


Availability of larger quantities varies by product. Email us with the product link, desired quantity, required specifications, and delivery location, and we will let you know whether suitable options are available.

How can I contact MROVanta?
