Skip-bonded tubing for the 0.675" and 0.85" Geotech Portable Bladder Pumps. Air and discharge lines are bonded together at intervals so a single run goes down the well and back without tangling.

Both small-diameter pumps use the same 0.17" x 1/4" line on the air and discharge sides, so one tubing size serves both. Sold by the foot — order your total depth plus working slack at surface.

Choosing a material

• LDPE — the standard, most flexible option and the easiest to handle on a reel in cold weather.
• HDPE — stiffer and more abrasion-resistant; holds up better in deep or rough casings.
• FEP-lined LDPE — an inert fluoropolymer flow path with a polyethylene outer wall. Use where the analyte list rules out direct contact with polyethylene.

See the matching 0.675" and 0.85" system collections for everything else that fits these pumps.
