LiteTouch® fittings
Dual-grip ferrule design for coned stainless-steel ports
The LiteTouch® Fittings System grips tubing at two compression points, holding to high pressures with fingertight convenience. It also prevents polymer tubing
from twisting, a potential problem when using standard fingertight fittings. LiteTouch® fittings are available for use with 1/32”, 1/16”, or 1/8” OD tubing sizes, and for 10-32 or 1/4-28 coned ports, preferably in stainless-steel.
For those space-limited applications where nut heads interfere with each other, try the FlushNut™ fittings which do require a tightening tool. To avoid collapsing the ID of your tubing, the LiteTouch® system can be used on hard tubing only, such as stainless steel and PEEK polymer tubing. Note that the LiteTouch® Ferrule System is not recommended for repeated use in plastic ports.
- Helps prevent twisting of polymer tubing
- High pressure with fingertight convenience
- Options available for 1/32”, 1/16”, or 1/8” OD tubing
Note:
A special type of fitting system sometimes included into the LiteTouch® family is the TinyTight™ fittings for 6-40 threaded MINSTAC port designs, which we have organized under flat-bottom fittings; see the products pages for TinyTight™ fittings.
