Labline® Mechanical Joint

Labline® (Mechanical Joint) has displaced the more expensive and difficult to install glass and metal systems.

  • Proven reliability
  • Easy to install
  • Can be disassembled and re-used

 

Labline acid waste systems deliver the proven corrosion resistance of our specially formulated polypropylene, and feature our state-of-the-art mechanical joining system using no-heat Elastolive, for high-integrity joints in seconds.

Ideal for modular systems that need to be periodically reconfigured, our Labline heavy-duty all thermoplastic fittings are designed to be reusable, should your system layout change. What’s more, Labline fittings are designed to prevent pipe pull-out and leaks due to misalignment, giving you unsurpassed versatility in designing your acid waste system.

PRODUCT DETAILS

Labline® acid waste systems are available in Schedule 40 and Schedule 80 pipe sizes from 1½" to 4" IPS. Both flame-retardant and non-flame-retardant pipe is available.

Labline (Mechanical Joint) has displaced the more expensive and difficult to install glass and metal systems. Gone is the need for fusing, caulking or welding of joints. Joining of the Labline System is complete in just 30 seconds and once the nut is locked into place, the end-user is assured of many years of trouble-free service. Yet, because it is a

mechanical joint, the system can be easily dismantled and re-used, making it ideal for modular designs and for systems that may require re-modeling in the future.

SPECIFICATIONS

GENERAL

Acid waste drain and vent system, as shown on drawings, shall be NSF listed, Schedule 40, polypropylene as manufactured by IPEX to include pipe supplied in 10 ft. lengths (or 20 ft lengths if NFRPP is specified), and matched fittings, traps and neutralization tanks from the same manufacturer. It shall also include recommended adapters to connect to other piping materials, where applicable.

MATERIAL

Pipe shall be made from NSF listed Type 1, flame retardant polypropylene conforming to ASTM D4101, with a maximum average flame spread of zero seconds and a maximum extent of burning of 13 mm, in accordance with ASTM D635. Matched fittings shall be made from NSF listed flame retardant polypropylene with average maximum burn time of 80 seconds and maximum extent of burning of 20 mm in accordance with ASTM D635. If NFRPP pipe is specified, it shall be made from NSF 14 listed and CSA certified Schedule 40 PP as manufactured by IPEX. Pipe shall comply with ASTM F1412 and material used shall comply with the material requirements of ASTM D4101.

FITTINGS

Fittings shall be NSF listed, be of all plastic construction and be designed to lock into a machined groove on the mating piping. All fittings shall have integrally molded union connections. No metallic grab rings or clamps shall be allowed. Fittings containing EVA (ethylene vinyl acetate) are strictly prohibited. Couplings shall not be added to make mechanical joint fittings. Fittings shall be Labline or approved equivalent. 

JOINTS

Connections between polypropylene pipe and matched fittings shall be made using the Labline Joint.

INSTALLATION AND TESTING

Installation and testing shall be in accordance with the contract drawings, the manufacturer’s recommendations and the local plumbing codes. Testing with compressed air is prohibited. The entire system shall be installed free of stress and in proper alignment. Horizontal supports shall provide a wide bearing area and be free of burrs or sharp edges. Support spacings shall be in accordance with the manufacturer’s recommendations and local plumbing codes. Vertical piping shall have riser clamps at each floor. Pipe supports shall be installed so that horizontal piping is in uniform alignment and with a uniform slope of at least 1/8" per foot, or in accordance with the local plumbing codes.
