PAVE Technology Co was founded in 1980. Its wire and connector hermetic seals are used in a very wide range of industries for low or high pressures or vacuums requiring helium gas tight seals or IP67 to IP69 seals. PAVE products feed through a sealed bulkhead either electrical or fiber optic signals without any detectable leakage of gases or fluids. This complete leak tightness performance includes ends of any insulated, shielded or stranded copper conductor wire, cable and/or pins. Major customers include:

3M Applied Biosystems Applied Materials Delphi Automotive Schlumberger Eaton Corp Auto/Aero Raytheon Company Alabama Power Corp Georgia Power Corp Lockheed Martin Corp Siemens Ford Motor Company ATK Corp BAE Corp Baker Hughes Beckman Instruments Emerson Corp Boeing Company NASA Parker Corp Guidant Corp Cooper Power Systems General Electric Corp BOC Edwards Corp FEI Corp Foxboro

PAVE products are used in a wide range of industries around the world including aerospace, low emission PZEV automotive and small engine (motorcycle, ATV, marine, etc) fuel pumps and transmissions, process controls, defense, telecommunications, semi-conductor and scientific instruments of all types requiring high quality seals. All our customers require high performance and cost effective standard or custom designed gas and fluid tight hermetic seals.

PAVE seals use virtually any commercial or military specification insulated wires and/or connector pins sealed in our proprietary epoxy process for a wide range of low and high pressures and vacuums, temperature ranges from -60 to 150C or 200C and from small to large quantity applications.

PAVE-Seal® and PAVE-Mate® Installation Insructions

« Previous

NPT PAVE-Seals: It is recommended that pipe threads be tightened 2 1/2 full turns past finger tight unless otherwise noted on PAVE drawings. Teflon tape or other thread sealant should be used.

Straight Thread PAVE-Seals (SO Type): Parker Hannifin Corp. tapping and counter-boring tools are recommended for proper port drilling. Please order these tools through your local Parker distributor. Tighten to 20 Ft. Lbs (27 Newton-Metre). Do not use Teflon tape on SO thread type penetrations.

Jam Nut/O-Ring (VS Type): The bulkhead surface sealing to the o-ring must be smooth (32 RMS finish or better), flat and perpendicular to the axis of the threads. The jam nuts should be tightened snug using 12 to 20Ft. Lbs. of maximum force (16-27 Newton-Metre). Excessive force is unnecessary and may damage the seal. The thruhole diameter should be the thread size or thruhole I.D. +.010",-.000" (+0,254mm, -0,000mm).

The preferred installation has the O-ring on the pressure or atmosphere side. The PAVE-Seal can also be installed into a tapped port without the jam nut. However, a small counter-bore in the bulkhead is may still be required on the o-ring side to properly seat the o-ring since there may not be a thread undercut in the VS housing. Jam nuts with a raised surface utilize special Spirolok® locking threads. Such nuts must be installed with the raised surface exposed or outward for proper locking and anti-vibration service.

Conflat® Type PAVE-Seals (CF Type): Available with either fluorocarbon (Viton) or OFHC copper gaskets, the maximum torque required to seal the flange is 16FT. Lbs(22 N-M)

Molded Epoxy piston o-ring PAVE-Seals: Port should be designed per standard o-ring handbook specifications for the appropriate o-ring size with proper 15 º lead-in, compression (usually 30%) and finish (32 RMS or better). Molded PAVE-Seal o-ring groove will have been properly de-flashed. Approved installation port dimensions are either in catalog or on PAVE drawing. If not sure of port dimensions, please ask for PAVE Sales Engineering assistance.

High Pressure Use: High (over 500 psi, 30 bar) or bi-directional pressures and/or temperatures sometimes require special design installation considerations. See PAVE drawings. PTN Hex Nipple PAVE-Seals which are to be subjected to these conditions are identified by a blue/black band encircling one thread end of the PAVE-Seal. The blue/black band indicates the high pressure end to which the extreme atmosphere is to be applied. High pressure ratings are not normally bi-directional. High pressure side is normally the hex side (o-ring to be pushed into bulkhead) or thread side (NPT). Customer should clearly indicate pressure direction at time of order to avoid improper installation and seal performance. Contact factory sales engineering before using in long term steam. No warranty for steam service exists without special certification from the factory.

O-rings should always be properly lubricated with a thin film. The O-ring on PAVE housings are normally lubricated at the factory with Swagelok Vac-Goop or Parker Super O-Lube or Parker O-Lube grease or otherwise noted on PAVE drawings.

IF A PROBLEM DEVELOPS, PLEASE CONTACT THE FACTORY QA Department (1-937-890-1100 x24) OR YOUR LOCAL SALES REP IMMEDIATELY. While very unusual, most leaks are due to either improper installation or thermal shocking the unit beyond its rated temperature. Our goal is to keep all of our customer satisfied, so let us know how we can help.
