At TUNSTALL  we specialize 
in the manufacturing of interior 
thermostatic elements for steam 
traps using state-of-the-art tech-
nology. For maximum reliability 
and long term performance our 
Tunstall Steam Trap Capsules
®
are made of a 10 plate TIG welded 
stainless steel bellows and feature 
orifice diameters up to 5/16”, 
custom tooling, a one-year war-
ranty, and pressure ratings from 
vacuum to 125 psig. Each capsule 
is individually tested and cali-
brated before shipment. Now you 
can economically increase the 
performance of your old steam 
traps by replacing the interiors 
with new Tunstall  technology. 
Made to retrofit almost all thermo-
static steam traps, Tunstall  Steam 
Trap Capsules
®
 are by far the best 
choice for repairing or upgrading 
existing traps. 
Having been in service since 1985, 
with virtually failure-free perform-
ance, Tunstall Capsules
®
 can offer 
your system years of trouble-free 
service.
