Features, Specs, and Performance of Max Adapter Compression Fittings
Get clear, measurable specs so you can pick the right coupling for each job without guessing.
These fittings use brass bodies designed for copper, aluminum, and thermoplastic pipe. For plastic tubing add the correct insert to maintain tube support and a proper seal.
Temperature range runs from -65°F to +250°F (-53°C to +121°C). That wide window covers cold basements and warmer mechanical rooms while staying within rated pressure limits.
Materials and Construction
Brass construction pairs with rubber sealing components for shear resistance and reliable sealing. Series stainless steel parts, including 304 series stainless, are available for corrosion-prone installations.
Operating Parameters
The couplings are intended for low- to medium-pressure liquid lines. They are not recommended for steel tubing or gaseous media. Vibration resistance is fair; choose a long nut if you need extra resistance to movement.
Standards and tolerances
Machining maintains +/- .02″ tolerance and complies with ASA, ASME, and SAE requirements. Light Pattern (“L”) options adjust thread length while still remaining interchangeable with full pattern parts.
- Not lead free; they’re intended for plumbing and light industrial work such as sewer repair and routine coupling swaps.
- Always inspect tube temperature ratings so components remain within the fitting’s specified envelope.
- Keep movement to a minimum to preserve ferrule grip and prolong rubber seal life.

Pipe Compatibility, Applications, and Installation Notes
Checking material compatibility before you cut tubing saves time and reduces the chance of leaks later on.
These couplings work with copper, aluminum, and thermoplastic tubing. If you use plastic tubing, you should add the proper insert to support the wall and maintain the seal.
Designed for low- to medium-pressure liquid lines, these parts fit fixture supplies, appliance hookups, and light sewer repair tasks. They are not rated for gaseous media or steel tubing, so you should avoid those applications to remain within safe limits.
Installation Tips
- Cut the tubing square and deburr lightly so the ferrule can seat evenly.
- Keep the tube axis aligned with the body and start the nut by hand to prevent cross-threading.
- Tighten gradually to the recommended turn-of-nut and recheck after pressurizing.
- In higher vibration areas, use a long nut and support neighboring runs to cut down movement.
- Maintain clearance for future service so the nut, ferrule, and cage are accessible for inspection or repair.
| Tube Material | Best Use | Notes |
|---|---|---|
| Copper / Aluminum | Fixture lines and appliance feeds | Straightforward installs with good sealing when torqued correctly |
| Thermoplastic | Low-pressure water runs | Requires insert to support the tube wall |
| Steel | Not recommended | Avoid use; select tube-rated couplings instead |
Trust Installation Parts Supply to deliver the right inserts, long nuts, and accessory parts for a smooth install. Follow the checklist—confirm tube material, add an insert for plastic, align properly, tighten to spec, and recheck—to reduce callbacks and keep jobs on schedule.

Common Questions
What types of pipes work with these compression connectors?
These compression connectors work with copper, aluminum, and many thermoplastic pipes, provided you use a proper insert for softer plastics. They are not intended for use with standard steel tubing or pressurized gaseous media. For cast iron, ductile iron, asbestos cement, and PVC sewers, check the product’s nominal diameter and sealing gasket compatibility before installing.
What materials are used in the construction?
The bodies are brass with stainless steel components in key areas, plus a pliable rubber sealing gasket to ensure leak resistance. Some variants include 304 series stainless steel parts and a high-impact securing cage or clamping system for added strength and durability.
How do these connectors perform under vibration and shear forces?
They are designed to withstand vibration and moderate shear forces, using steel click-lock clamping and a cast iron or ductile iron rated cage in heavy-duty models. A rubber sealing gasket maintains a tight seal, and the clamping system absorbs movement to reduce the chance of joints loosening.
Can these fittings be installed in cold conditions?
Yes. The rubber gasket remains flexible for easier installation during cold weather, and stainless steel parts resist embrittlement. To get the best outcome, follow torque guidelines carefully and give yourself extra time for alignment in very cold temperatures.
What are the operating pressure and temperature limits?
These connectors generally operate in low-to-medium pressure plumbing applications and temperature ranges from about -65°F to +250°F for compatible materials. Always confirm the specific model’s rating, particularly when working close to the upper temperature or pressure limits.
Do these connectors comply with industry standards?
Many meet ASA/ASME/SAE tolerances with tight dimensional control (often +/- .02). Check model certifications and material listings to ensure compliance with your project’s codes.
Are pipe inserts necessary when using plastic pipe?
Yes, for most thermoplastic pipes you should use an insert to prevent deformation and ensure proper sealing. The insert helps maintain alignment and reduces risk of leak or failure under pressure.
How do I ensure proper pipe alignment during installation?
Clean and square the pipe ends, use a guide or insert on plastics, and engage the click-lock clamping evenly. With the securing cage and high-impact clamping system, alignment is maintained as you tighten to the recommended torque values.
Can these connectors be used for sewer repair and gravity flow systems?
Yes, certain models are suitable for sewer repair and gravity flow drainage provided they’re sized correctly for the nominal diameter and the rubber sealing gasket is compatible with wastewater. Be sure to verify compatibility with iron, cast iron, and asbestos cement pipe types if they are present in the system.
How do pricing and availability work when ordering online?
Because pricing often follows MAP policy, the lowest available price usually appears in your cart at checkout. Installation Parts Supply and similar vendors list related options like angle stop valves and cost-saving combos; compare those to choose the best solution for your budget and job.
What related options should I consider for cost savings?
Look for bundled valve-and-coupling combos, angle stop adapters, and multi-pack offers. Choosing stainless steel click-lock models only where necessary can save money while keeping steel components where strength is critical.
How long will the rubber sealing gasket last in sewer or drainage service?
Service life depends on exposure to chemicals, abrasion, and temperature. In typical sewer and gravity-flow applications, a high-quality rubber gasket paired with stainless steel components can last many years. Inspect periodically and replace if you see hardening or cracking.
