PumpToys standard quick-disconnect or "SD" hose coupler system fits to 1/8" NPT threading in the cylinder. Part numbers for the standard couplings end in ".18". This is the coupler design used by virtually all makers of pumps and cylinders. All PumpToys products use the .18 coupler; thus all our products are compatible with your other brand cylinders and pumps.
PumpToys (and most manufacturers) use o-ring seals between the cylinder and connector; the O-ring is included when you order a body part. All line insert (SD, male) couplers have a 1/4" barb type hose connection, designed to insert directly into tubing with a 1/4" ID or inside diameter. Vac line may be ordered below.

With this seal, you can have a pump that is as effective and more comfortable than any standard two-stage cylinder, for a total investment of LESS THAN $40.00!
