Plastic Lined Fittings

Plastic Lined Fittings and Pipe Details


You can find all the dimensional characteristics as well as liner and housing availability from LinedPipe.Com here. The tables list the sizes we commonly fabricate; other sizes and configurations are quoted on request. All dimensions are in inches and refer to the letters on each drawing. Carbon steel housings are standard; 304 and 316 stainless are available on every item, and most shapes are also available with polypropylene or PVDF liners. PTFE and PVDF are the materials many people know by the trade names Teflon and Kynar. Have questions? Get in touch with us.

PTFE lined pipe spools are lined with a high quality paste extruded liner. The pipe is A587, A106 or A53 carbon steel with stainless steel available as an option. Standard spools come with two rotating flanges. Fixed flanges can be ordered if desired. Spools can be specified in lengths up to 20 feet.

Marspec has over 50 years experience in fabricating custom-length pipe spools in our own shop on the Eastern Shore of Mobile Bay.
