Specifications
1. PVC MATERIAL SPECIFICATIONS PVC Type I, or Type II
meeting requirements of ASTM D-1784-75 is used in the
manufacturing of all fittings recommended for use of
potable cold water (see chart C for temperatures vs.
pressure). Not recommended for use on systems exceeding
100 psi at 120 degrees F.
2. CPVC MATERIAL SPECIFICATIONS CPVC Type IV,
meeting requirements of ASTM D-1784-75 is used in the
manufacturing of all fittings recommended for use on
potable hot water systems in accordance with
ASTM D-2846-73. Not recommended for use on systems
that will exceed 100 psi at 180 degrees F.
3. EPDM O-RINGS The O-ring material is made of high
quality EPDM (Ethylene Propylene Copolymer) which
meets the requirements of ASTM D-200. EPDM has
exceptionally good weather aging and ozone resistance,
excellent water and chemical resistance, and excellent
aging resistance for most applications. EPDM is a polymer
where oil and solvent resistance is poor. However, it
is fairly good in ketones and alcohols. Reference chemical
resistance under EPDM, EPT, or EPR Elastomers for
specific listings.
4. DOUBLE SEAL of standard compression fitting. A
compressive action is created as the cap is tightened,
squeezing the EPDM seals into the tapered recesses
areas of the cap and body. This process creates a highly
concentrated pressure at the two “double seal” points,
thus providing positive protection against leakage.
5. ACME THREAD General purpose 10 pitch Acme thread
on compression cap section eliminates the possibility of
cross threading. The smooth running design prevents
binding or galling as is often experienced in standard
tapered threads.
6. COMPRESSION CONNECTIONS Compression cap
should be drawn up hand tight to ensure proper alignment
and seating of gasket, then tightened 3/4 to 1 turn
with a wrench or strap wrench. Average torque should
be approximately 25 foot pounds on 1/2” through 2” IPS,
and 35 foot pounds on 2-1/2” and larger IPS. Compression
fittings are not recommended for use on compressed air
lines or natural gas lines.
7. THREAD CONNECTIONS Use teflon tape on all IPS
thread connections. IPS thread connections should be
made hand tight plus 1/2 to 3/4 turn with a wrench.
8. THRUST BLOCKING When installing the standard compression
seal fittings the pipe line must be restrained
from lateral movement by thorough soil compaction on
straight runs and thrust blocking at change of direction or
reduction in size. Not recommended for use on pipe lines
suspended on hangers.
9. K-LOC COMPRESSION ADAPTERS Recommended for
use on PVC pipe with wall thickness of SDR-26, Class 160
or greater and copper tubing. Not recommended for use
on galvanized pipe unless surface is sanded smooth. The
gripper ring is made of stainless steel.
10. ALL SPRINGS Made of Series 302 stainless steel.
