Scope: To test and report the leak rate of RLS press connections.
Background: Marmon Refrigeration Technologies (MRT) submitted RLSTM press connection samples for
helium leak testing. Six (6) different RLS TM sizes were chosen to connect commercially available ACR
tubing (see Table 1). Thirty (30) union connections were chosen as a sample lot with two (2) connections
per fitting. Each sample connected two pieces of tubing approximately nine (9) inches long. One of the
tubes was brazed shut at one end and the other tube was reduced to a tube stub.

Notes
Samples were made from
commercially available
ACR tubing (soft)
EWI Leak Testing Approach: Prior to testing each lot of samples, the Veeco MS-40 helium leak tester
was calibrated. After calibration, a solid dowel was tested to verify the integrity of the seals on the
helium leak test fixture.
The tube stub was wiped down with methanol and connected to the leak detector a via a Swagelok
Ultra-Torr vacuum fitting (see Figure 1). Each sample was pumped down to a level of approximately 500
millitorr prior to applying helium gas near the RLS TM crimp joint (at atmospheric pressure). The helium leak
rate was measured and recorded for each of the sixty (60) connections in a thirty (30) piece sample lot.

Methodology
A time study was conducted in a controlled environment, with two
stations set up for joining refrigeration tube: one by brazing and one
by using ZoomLock braze-free fittings. Two different installers were
used, one very experienced in making brazed connections and one very
experienced in using the ZoomLock press tool.
The two installers were timed independently making connections using
various sized copper tube and fittings. Before timing began, tube was cut
to length and the ends were prepared for connection (as these procedures
are the same for both connection methods). Three connections were
timed for each size of tube/fitting for each installer, and the three times
were averaged. The results are shown in the table below.
