 Dry Disconnect – 1" Adaptor Maintenance

1" DRYLOK ADAPTORS:

 

WARNING

 

OPW ENGINEERED SYSTEMS cannot be held 

responsible for the integrity of a Field rebuilt product. To minimize the 
possibility of physical injury and obtain the best possible functioning 
product after rebuilt, it is strongly recommended that the procedures 
outlined be followed to Tear down, Re-assemble and Test the product 
before placing the unit back into service. Reference the enclosed illus-
trations to facilitate identification of parts. 

TEAR DOWN INSTRUCTIONS:

1.  

    

Clamp the ADAPTOR (1) in vise with soft jaws, with the threaded end 
pointing up towards you. Take care not to mar machined surfaces of 
ADAPTOR NOSE (1).

2.

  Using needle nose pliers, unthread BRIDGE (2) from ADAPTOR (1), 

exercising care and caution. POPPET ASS’Y (3) in valve is spring 
loaded. SPRING force on the 1" Drylok adaptor is approximately  
28 pounds.

3.

  Remove POPPET ASS’Y (3) and SPRING (4).The POPPET ASS’Y is not 

included in the Repair Parts Kit. It will be necessary to replace the  
old O-RING (5).

4.

  Position POPPET ASS’Y (3) in collet or vise with soft jaws. Carefully 

pry O-RING (5) out of the POPPET ASS’Y groove (be careful not to 
scratch the groove seat with the prying tool. This could result in an 
O-RING leak). Discard old O-RING.

RE-ASSEMBLE INSTRUCTIONS:

5.  

    

Re-assemble POPPET ASS’Y (3) and new ORING (5)  
in the following manner:

 

a)  Position new O-RING (5) on top of POPPET ASS’Y (3).

 

b)  With your thumb, press a section of the O-RING 

into the groove.

 

c)  Press the O-RING around the POPPET ASS’Y and over the 

groove lip (it is necessary to slightly stretch the O-RING to 
accomplish this).

 

d)  Continue pressing the O-RING around the POPPET ASS’Y 

until the O-RING is seated in the groove.

NOTE:

 Teflon encapsulated O-RINGS should be heated in hot water for 

easier installation.

6.

  Install rebuilt POPPET ASS’Y (3) with O-RING (5) into ADAPTOR (1). 

Install SPRING (4) behind POPPET ASS’Y (3). Thread BRIDGE (2) into 
ADAPTOR (1). Poppet shaft should fit into BRIDGE (2) bore freely.

7.

  Once started, thread BRIDGE (2) all the way into ADAPTOR (1) until 

it abruptly stops and will tighten no further. Again, take care not to 
mar machined surfaces of ADAPTOR (1). TEST PROCEDURE

It is recommended that the VALVE be pressure tested utilizing the air 
under water method, checking for leaks in the area of the POPPET seat. 
Air pressure must not exceed 30 PSI. If pressurized air is not available, 
low pressure leaks could be checked by submerging the entire ADAP-
TOR face up in a container of clear water. Air trapped inside the VALVE 
will bubble through or around the POPPET if the seal is not proper. This 
test should be repeated three or four times to ensure that the seal does 
not leak. Depress and release the POPPET each time before submerging 
the unit into water.
